Conflicts:
- `spec/lib/sanitize/config_spec.rb`:
Upstream rewrote top-level `describe` calls to `RSpec.describe`, and
glitch-soc had differences in the first few tests because of the wider
subset of HTML it accepts.
Changed `describe` to `RSpec.describe` as upstream did, keeping
glitch-soc's tests.
Conflicts:
- `spec/requests/api/v1/timelines/tag_spec.rb`:
Upstream refactored this file, while we had a change to switch a default setting.
Updated as upstream did.
- `spec/views/statuses/show.html.haml_spec.rb`:
Upstream refactored this file, while we stubbed different methods.
Updated as upstream did, and updated the stubs accordingly.
