In the absence of an opt-in to multiple specific languages in the
preferences, it makes more sense to filter by the user's presumed
language only (interface language or `lang` override)
Conflicts:
- `app/models/public_feed.rb`:
Upstream refactored a bit, glitch-soc had specific code for local-only
statuses.
Updated glitch-soc's specific code accordingly.
* disable NewCops
* update TargetRubyVersion
* Fix Lint/MissingSuper for ActiveModelSerializers::Model
* Fix Lint/MissingSuper for feed
* Fix Lint/FloatComparison
* Do not use instance variables
Conflicts:
- app/controllers/api/v1/timelines/public_controller.rb
- app/lib/feed_manager.rb
- app/models/status.rb
- app/services/precompute_feed_service.rb
- app/workers/feed_insert_worker.rb
- spec/models/status_spec.rb
All conflicts are due to upstream refactoring feed management and us having
local-only toots on top of that. Rewrote local-only toots management for
upstream's changes.
