When you issue /retest on a Merge request, it works in both gitlab and github.

When you issue /retest on a commit as in these instructions: https://github.com/redhat-appstudio/docs.appstudio.io/pull/237/files, it works on github - but it does not seem to work in gitlab.

It didn't work here: https://gitlab.com/redhat/centos-stream/containers/bootc/-/commit/c41148a44f5480d8023a50d10303b46d93a7fe9f
