This Pull Request addresses a race condition in the updateIframeHeight
function where it is sometimes called when the iframe is not fully
loaded or accessible resulting in an alarming error message for the
user.
To address this we:
1. Add defensive programming within the updateIframeHeight function
2. Delay instantiating the intersection observer until the iframe has
loaded

Update mermaid to
[v11](https://github.com/mermaid-js/mermaid/releases/tag/v11.0.0) and
enable the new [`suppressErrorRendering`
option](https://github.com/mermaid-js/mermaid/pull/4359) to ensure
mermaid never renders error elements into the DOM (we have per-chart
error rendering, so don't need it). Tested various chart types.
BTW, I was unable to reproduce that error rendering from mermaid with
`suppressErrorRendering: false` and I thought we had some CSS to hide
the error element, but I could not find it, not even in git history.
None of the frontend js/ts files was touched besides these two commands
(edit: no longer true, I touched one file in
61105d0618
because of a deprecation that was not showing before the rename).
`tsc` currently reports 778 errors, so I have disabled it in CI as
planned.
Everything appears to work fine.
We have to define this one in helpers.css because tailwind only
generates a single class but certain things rely on this being
double-class. Command ran:
```sh
perl -p -i -e 's#gt-hidden#tw-hidden#g' web_src/js/**/* templates/**/* models/**/* web_src/css/**/*

Some minor refactors, remove unnecessary `:is` selector and move the
`:target` check out of the function. Might as well backport for the rare
browser that does not support `:is`.
This seeks to fix the bug reported on issue #29196.
Cause:
ID's with custom characters (- , _ , etc.), were not linking correctly
in the Markdown file when rendered in the browser because the ID in the
respective destinies would be different than the one in anchor, while
for IDs with only letters, the ID would be the same.
Fix:
It was suggested that to fix this bug, it should more or less like
GitHub does it. While in gitea the anchors would be put in HTML like
this:
```
<p dir="auto"><a href="#user-content-_toc152597800" rel="nofollow">Review</a></p>
<p dir="auto"><a href="#user-content-_toc152597802" rel="nofollow">Staging</a></p>
<p dir="auto"><a href="#user-content-_toc152597803" rel="nofollow">Development</a></p>
<p dir="auto"><a href="#user-content-_toc152597828" rel="nofollow">Testing</a></p>
<p dir="auto"><a href="#user-content-_toc152597829" rel="nofollow">Unit-tests</a></p>
```
In GitHub, the same anchor's href properties would be the same without
"user-content-" trailing behind.
So my code made sure to change those anchors, so it would not include
"user-content-" and then add respective Event Listeners so it would
scroll into the supposed places.
Fixes: #29196

Behaviour now matches GH. Safeguard added in the for loop because
`textContent` may be null in which case it does not make sense to render
the copy button.
Fixes#25160.
`data-source-position` of checkboxes in a task list was incorrect
whenever there was YAML front matter. This would result in issue content
or PR descriptions getting corrupted with random `x` or space characters
when a user checked or unchecked a task.
As discussed in #22847 the helpers in helpers.less need to have a
separate prefix as they are causing conflicts with fomantic styles
This will allow us to have the `.gt-hidden { display:none !important; }`
style that is needed to for the reverted PR.
Of note in doing this I have noticed that there was already a conflict
with at least one chroma style which this PR now avoids.
I've also added in the `gt-hidden` style that matches the tailwind one
and switched the code that needed it to use that.

In #22447 it was noticed that display environments were not working
correctly. This was due to the setting displayMode not being set.
Further it was noticed that the error was not being displayed correctly.
This PR fixes both of these issues by forcibly setting the displayMode
setting and corrects an error in displayError.
Fix#22447

- Add Copy button to mermaid diagrams which copies their source.
- Set tippy to not hide on click and avoid tooltip re-creation for
temporary tooltips. This avoids hide and show when copying repo url.
Popovers still hide the tooltip as usual.

The hashchange event did not fire on re-click of a active anchor.
Instead, use the click event which always fires.

When starting a scroll while the mouse is over a mermaid diagram, the
scroll sometimes propagates to the iframe, preventing the parent page
from scrolling. Fix this by disabling scroll inside the iframe. This is
not a problem because those frames are never meant to scroll. Bug seems
to affect Firefox only.
Browsers introduce a opaque background on iframes if the iframe
element's color-scheme does not match the document's color scheme which
in case of a dark theme results in a mismatch and the browser adds a
white background. Avoid this by specifying the same color scheme outside
and inside the iframe.
See https://fvsch.com/transparent-iframes for more info.
My initial attempt was to make the iframe document the same color-scheme
as the parent page (light or dark) but with that, there was a ugly
background flash on load in Chrome because Chrome apparently always
loads iframe in light scheme initially. Firefox still shows a background
flash on load but this is not possible to get rid of and it's certainly
a browser bug.

This PR adds mathematical rendering with KaTeX.
The first step is to add a Goldmark extension that detects the latex
(and tex) mathematics delimiters.
The second step to make this extension only run if math support is
enabled.
The second step is to then add KaTeX CSS and JS to the head which will
load after the dom is rendered.

* Add new JS linter rules
Adds a few useful rules from eslint-plugin-github. Notable changes:
- Forbid dataset usage, its camel-casing behaviour makes it hard to
grep for attributes.
- Forbid .then() and .catch(), we should generally prefer await for new
code. For rare cases where they are useful, a eslint-disable-line
directive can be set.
- Add docs js to linting
* also enable github/array-foreach
* small tweak
