Merge commit 'c91c0175db1cc8b954a977d29472886234ce9586' into glitch-soc/merge-upstream

Conflicts:
- `spec/controllers/api/v1/timelines/tag_controller_spec.rb`:
  Glitch-soc had a few extra lines in this file to account for a different
  default setting. This file got replaced by
  `spec/requests/api/v1/timelines/tag_spec.rb`, into which the glitch-soc
  additions were moved too.

Additional changes:
- `spec/requests/api/v1/statuses/sources_spec.rb`:
  Add glitch-soc-only attribute `content_type`.
