[PATCH] gitlab: switch from 'stable' to 'latest' docker container tags

[Daniel P . Berrangé]

The 'stable' and 'stable-dind' tags are not documented as supported
tags at:

  https://hub.docker.com/_/docker

Looking at their content they reflect docker 19.x.x release series,
were last built in Dec 2020, and have 3 critical and 20 high rated
CVEs unfixed. This obsolete status is attested by this commit:

  
https://github.com/docker-library/docker/commit/606c63960a4845af7077721eb3900c706f5d0c5e

The 'stable-dind' tag in particular appears buggy as it is unable to
resolve DNS for Fedora repos:

  - Curl error (6): Couldn't resolve host name for 
https://mirrors.fedoraproject.org/metalink?repo=fedora-37&arch=x86_64&countme=1 
[getaddrinfo() thread failed to start]

We used the 'stable' tag previously at the recommendation of GitLab
docs, but those docs are wrong and pending a fix:
