rpmbuilder's vendored third-party RPMs are moving from Gitea's RPM registry
to the artifactapi rpm-vendor local repos. Managed AlmaLinux hosts need the
matching yum repo to install them; this mirrors the existing rpm-internal
repo and selects the per-EL-release repo via os.release.major.
- Add rpm-vendor to profiles::yum::global::repos in
hieradata/os/AlmaLinux/all_releases.yaml, pointing at
.../api/v1/local/rpm-vendor-el<major>/ (el8/el9), gpgcheck disabled and
mirrorlist absent, matching the rpm-internal repo definition.
