In case you are developing a set of changes in a module, in conjunction with a branch in gst-ci, you will end up with a template with a different tag than the upstream repo, which will be refferencing your gst-ci forked registry. But that image won't existin in the namespace the module would be running at, so we need to copy it from there. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-ci/-/merge_requests/308>
