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

Conflicts:
- `app/controllers/accounts_controller.rb`:
  Upstream change too close to a glitch-soc change related to
  instance-local toots. Merged upstream changes.
- `app/services/fan_out_on_write_service.rb`:
  Minor conflict due to glitch-soc's handling of Direct Messages,
  merged upstream changes.
- `yarn.lock`:
  Not really a conflict, caused by glitch-soc-only dependencies
  being textually too close to updated upstream dependencies.
  Merged upstream changes.
