Remove gitlab_ui_wg specific Dangerfile
What does this MR do?
This MR removes a special Dangerfile exception for MR's with a CSS Cleanup
label. This seems to add unnecessary complexity and inconsistency to our reviewer selection process.
Why remove this?
- This might have been necessary when
gitlab-ui
was in its early stage. But now it's just confusing. - Also, it's coupled with a
CSS Cleanup
label which isn't used consistently to represent GitLab UI working group changes. - Also, it has hard coded references to people regardless of availability.
