Show an Alert that a user is not using deployments [RUN ALL RSPEC] [RUN AS-IF-FOSS]

What does this MR do?

If a user edits a gitlab ci file, we try to investigate it to see if there are any environments used.

If not, a tip alert pops up suggesting users check out environments and deployments.

If the user dismisses the alert, it is permanently dismissed.
