Merge branch 'main' into glitch-soc/merge-upstream

Conflicts:
- `.prettierignore`:
  Upstream added a line at the end, glitch-soc had extra entries at the end.
  Added upstream's new line before glitch-soc's.
- `Gemfile.lock`:
  Upstream updated dependencies while glitch-soc has an extra one (hcaptcha).
  Updated dependencies like upstream did.
- `app/controllers/api/v1/statuses_controller.rb`:
  Not a real conflict, upstream added a parameter (`allowed_mentions`) where
  glitch-soc already had an extra one (`content_type`).
  Added upstream's new parameter.
- `app/javascript/styles/fonts/roboto-mono.scss`:
  A lot of lines were changed upstream due to code style changes, and a lot
  of those lines had path changes to accomodate glitch-soc's theming system.
  Applied upstream's style changes.
