Red Hat 9 and workalike support (Rocky/Alma/CentOS 9)

I am trying to install GitLab using the instructions for Red Hat - like operating systems on Rocky Linux 9.

Although all steps succeed, except only a warning that the (I think obsolete) pygpgme package is not available, no gitlab packages are apparently available to install. I tried bor both the ee and ce editions. A search for “gitlab” in the resulting repositories does not seem to find either gitlab-ee or gitlab-ce:

dnf search gitlab

Is GitLab supported on RHEL 9 or workalike OS’es?

Update: I can install the EL 8 versions on EL 9 by changing the 9 to 8 manually in the repository setup files:

gitlab_gitlab-ce.repo:baseurl=https://packages.gitlab.com/gitlab/gitlab-ce/el/8/$basearch

gitlab_gitlab-ce.repo:baseurl=https://packages.gitlab.com/gitlab/gitlab-ce/el/8/SRPMS

This is a workaround I suppose. Everything seems to work. An update to support EL 9 would be useful, however.
