gitlab-rails: disable remove ACE via cleanup-gems
It was found in gitlab-org/charts/gitlab#1940 (closed) that we could not run asset compilation within our pipeline due to a corruption of the cached Gem vendor/bundle
cache.
In order to re-enable that, we're disabling the removal of ace-rails-ap
Gem's vendor/assets folder which contains all of the actual ACE Javascript libraries.
