Conflicts:
- `.github/dependabot.yml`:
  Upstream made changes, but we had removed it.
  Discarded upstream changes.
- `.rubocop_todo.yml`:
  Upstream regenerated the file, we had some glitch-soc-specific ignores.
- `app/models/account_statuses_filter.rb`:
  Minor upstream code style change where glitch-soc had slightly different code
  due to handling of local-only posts.
  Updated to match upstream's code style.
- `app/models/status.rb`:
  Upstream moved ActiveRecord callback definitions, glitch-soc had an extra one.
  Moved the definitions as upstream did.
- `app/services/backup_service.rb`:
  Upstream rewrote a lot of the backup service, glitch-soc had changes because
  of exporting local-only posts.
  Took upstream changes and added back code to deal with local-only posts.
- `config/routes.rb`:
  Upstream split the file into different files, while glitch-soc had a few
  extra routes.
  Extra routes added to `config/routes/settings.rb`, `config/routes/api.rb`
  and `config/routes/admin.rb`
- `db/schema.rb`:
  Upstream has new migrations, while glitch-soc had an extra migration.
  Updated the expected serial number to match upstream's.
- `lib/mastodon/version.rb`:

  glitch-soc has an extra `+glitch` tag.
  Changed the code to support upstream's feature but prepending a `+glitch`.
- `spec/lib/activitypub/activity/create_spec.rb`:
  Minor code style change upstream, while glitch-soc has extra tests due to
  `directMessage` handling.
  Applied upstream's changes while keeping glitch-soc's extra tests.

  Minor code style change upstream, while glitch-soc has extra tests.
