## Problem The file trigger rule for rubocop in lefthook is incomplete. It will causes errors that should be reported in lefthook to be delayed in the pipeline. ## Reproduce Add content to `Gemfile` that does not match the rubocop rules, and then check it with `lefthook run pre-push`. lefthook will skip the rubocop check because of `NO FILES FOR INSPECTION`. ## Solution - Remove the rubocop [filter](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lefthook.yml#L38) from `lefthook`. - Synchronization rules to rubocop [filter](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lefthook.yml#L39) in lefthook.
