Move ee_compat_check to an earlier build stage?
Currently this task runs as part of the test
stage, which means that when a reviewer gets to the MR, they might set Merge When Pipeline Succeeds while the test stage is still shown as "in progress" and it's easy to miss a failed EE compat check, since the icon for "in progress" gets priority.
If we move this to the prepare
stage, it will finish sooner and might be more obvious that an EE version needs to be opened.
A real-world example of this appears to have happened in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/14525
