Versions that has branched out from Rawhide but are still not released
still have many changes that breaks the CI.
As we want the CI to be more stable for Tier 1, which runs for every MR,
do not make the switch as soon as Rawhide has branched, but when we choose so.
Useful to have easily accessible the info of all the distros that we
test, including the version of NM that they ship and their EOL dates so
we can know when to stop testing them.
For now this is only informative, but we can use this info, for example,
to generate the `.gitlab-ci/config.yml` file automatically for each
stable branch.
