ci: Don't depend on permutation jobs for coverage

What does this MR do and why?

Permutation jobs are duplicate of the canonical jobs, so they shouldn't result in any coverage difference.

This will reduce the number of jobs we depend on in the pipelines that run permutation jobs.

For instance, we can see that in https://gitlab.com/gitlab-org/gitlab/-/jobs/4064015061 and https://gitlab.com/gitlab-org/gitlab/-/jobs/4064015067, we download artifacts from 516 jobs!
