Commits like the following changed the script names and distro tag
but didn't update the documentation. We do not explicitely mention
script names because they will likely change in the future but the
distro tag is less likely to change because it is shared with the
upstream ci-templates repo.

Fixes: af7dca35 ("ci: Update the ci-templates commit.")
Fixes: 506e9d5f ("gitlab-ci: Rename container install scripts to ...")
Fixes: c6c76527
