Fix a wrong assets image name for gitlab-ee on 'dev'
What does this MR do?
This should fix outdated assets in EE nightly images since the single codebase migration! Investigation was initially performed in https://gitlab.com/gitlab-org/quality/nightly/issues/142#note_218062707 and consolidated in #32280 (closed).
Closes #32280 (closed)
