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

Conflicts:
- `app/controllers/accounts_controller.rb`:
  Upstream introduced support for private pinned toots, but glitch-soc's query
  was a bit different as it filtered out local-only toots.
  Used upstream's query, while adding local-only filtering back.
- `app/controllers/activitypub/collections_controller.rb`:
  Same thing with regards to local-only posts.
- `app/validators/status_pin_validator.rb`:
  Not a real conflict, but the line below was different in glitch-soc due to
  the configurable pinned toots limit.
