Add test to make sure the archive doesn't fail when event for event relation is missing and not included in list of provided events. Like if someone is replying to an event that was from long ago out of our range.
In the case of missing relations, Hydrogen does `_loadContextEntryNotInTimeline` because it can't find the event locally which throws an `uncaughtException`. Before https://github.com/matrix-org/matrix-public-archive/pull/51, the `uncaughtException` killed the Hydrogen `child_process` before it could pass back the HTML. Now this PR mainly just adds a test to make sure it works.

1. Build test homeserver Docker images which can federate with each other
2. Run end-to-end (e2e) tests
#### Dev notes
Sharing variables across jobs when the `services` field can't access the `env` context, https://github.community/t/how-to-use-env-with-container-image/17252/24
```yaml
env:
FOO: bar
jobs:
set_env:
outputs:
var: ${{ steps.save_var.outputs.var }}
steps:
- id: save_var
run: echo "::set-output name=var::${{ env.FOO }}"
actual_job:
needs: set_env
container:
image: ...whatever_you_need_here...${{ needs.set_env.outputs.var }}
```
Remove `matrix-bot-sdk` usage in tests because it didn't have timestamp massaging `?ts` and it's not really necessary to rely on since we can just call the API directly 🤷. `matrix-bot-sdk` is also very annoying having to build rust crypto packages.
We're now using direct `fetch` requests against the Matrix API and lightweight `client` object.
All 3 current tests pass ✅
