Many files do not directly depend on jQuery now.
To clarify the usage: use `fomanticQuery` to operate Fomantic
components.
Then developers could focus on removing the remaining jQuery usages by
searching `import $` globally.
21 files now:
```
./components/RepoBranchTagSelector.vue:3:import $ from 'jquery';
./features/admin/common.ts:1:import $ from 'jquery';
./features/admin/emails.ts:1:import $ from 'jquery';
./features/common-button.ts:1:import $ from 'jquery';
./features/comp/ComboMarkdownEditor.ts:3:import $ from 'jquery'; (I am working on it, there will be a new PR)
./features/comp/LabelEdit.ts:1:import $ from 'jquery';
./features/notification.ts:1:import $ from 'jquery';
./features/org-team.ts:1:import $ from 'jquery';
./features/repo-code.ts:1:import $ from 'jquery';
./features/repo-common.ts:1:import $ from 'jquery';

./features/repo-issue-sidebar.ts:1:import $ from 'jquery';
./features/repo-issue.ts:1:import $ from 'jquery';
./features/repo-legacy.ts:1:import $ from 'jquery';
./features/repo-new.ts:1:import $ from 'jquery';
./features/repo-projects.ts:1:import $ from 'jquery';
./features/repo-settings.ts:1:import $ from 'jquery';
./features/repo-template.ts:1:import $ from 'jquery';
```
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.
