Show commits to main branch since tag/release

Very similar to gitlab-foss#29648 (closed) where we can manually compare two given commits, e.g. gitlab-playground/tag-changes@v1.0...03333939, it would be a great feature, if there would be a comparison straight from the detail view of a given tag, as GitHub is doing it:
