Upgrade `gilab-styles` to 9.2.0

What does this MR do and why?

Upgrade gitlab-styles to 9.2.0.

See https://gitlab.com/gitlab-org/ruby/gems/gitlab-styles/-/releases/v9.2.0 for the changelog.

This MR also generates TODOs for all new/changed cops and put them in "grace period" as per https://docs.gitlab.com/ee/development/rubocop_development_guide.html#enabling-a-new-cop.

Two RuboCop offenses were fixed in HAML as the RuboCop TODOs won't work there 😞
