During a security release we can't deploy new versions of independent projects like registry
When bumping the container registry version during a security release, deployments unexpectedly fail because the matching container registry image can't be found on dev.
The reason for this is probably that we stop mirroring https://gitlab.com/gitlab-org/build/CNG to dev during a security release and thus don't build new images there during that time.
We should determine why we need to stop syncing to dev during a security release and find a way to prevent that we try to deploy versions for which we don't have images on dev.
