Gitlab-monitor image not properly referenced in 12.0.0 release
Summary
The image we are building is the 4.0.0 tag in CNG images, but the image we requested in the 12.0.0 release was the v12.0.0
image tag.
To have the release work, I tagged the 4.0.0 image as v12.0.0
but for future patches, we need to fix the release process, likely tagging monitor as the gitlab release in CNG imags automatically.
