Conflicts:
- `.rubocop_todo.yml`:
Upstream re-generated the file, while glitch-soc has a specific ignore
for some file.
Updated the file as upstream did and kept our extra ignore.
- `config/webpack/shared.js`:
Upstream added a plugin, but our files are pretty different.
Added the plugin as well.
- `spec/helpers/application_helper_spec.rb`:
Upstream refactored tests, but part of them were different because
of glitch-soc's theming system.
Applied the refactoring to glitch-soc's change.
