Comment from the testing pipeline
This change allows gitlab-org/security/gitlab to trigger the testing pipeline.
The plan is to speed up jobs by pre-packing the migrations in the GitLab pipeline and pulling an image ready-to-use, instead of cloning the repo in every job. This will be handled in a follow-up.
Closes #50
