Conflicts:
- `app/controllers/auth/registrations_controller.rb`:
  Not a real conflict. Upstream removed the `set_instance_presenter` private
  method from this class, and glitch-soc has an extra private method right
  besides it for the theming system.
  Removed `set_instance_presenter` as upstream did.

Merge commit '2016c5d912f400ae98ee03ce269112de2f9ec62d' into glitch-soc/merge-upstream

Conflicts:
