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

Conflicts:
- `app/models/account.rb`:
  Conflict because we (glitch-soc) have disabled trending of posts without
  review.
  Discarded that upstream change.
- `app/views/admin/settings/discovery/show.html.haml`:
  Just an extra setting in glitch-soc.
  Kept that extra setting.
