Conflicts:
- `app/models/user_settings.rb`:
Upstream added a constraint on a setting textually close
to glitch-soc-only settings.
Applied upstream's change.
- `lib/sanitize_ext/sanitize_config.rb`:
Upstream added support for the `translate` attribute on a few elements,
where glitch-soc had a different set of allowed elements and attributes.
Extended glitch-soc's allowed attributes with `translate` as upstream did.
- `spec/validators/status_length_validator_spec.rb`:
Upstream refactored to use RSpec's `instance_double` instead of `double`,
but glitch-soc had changes to tests due to configurable max toot chars.
Applied upstream's changes while keeping tests against configurable max
toot chars.
