Disable broken migration referenced FK ci_job_artifacts

Ref: #435801 (closed)

What does this MR do and why?

This MR disables broken migrations introduced in !140960 (merged) as the FKs being validated do not exist for self-managed yet.

We first need to create those FK for self-managed before validating them.

We did not noticed this broken job as it is allowed to fail.
