Adopt GitLab CI template

Probably best to squash on commit

left some comments.

Personally I would definitely recommend to not do that much in a single MR, it's impossible to review. I only scrolled through a bit.

My preferred approach is to just enable tests with required test fixes and everything else in follow-ups, it's just warnings. But it's a bit late for that now, your call.

After some thought decided to proceed with it and tag a 2.0.x branch.

Drafted a release note for when the first release is tagged on the 2.0.x branch: https://www.drupal.org/node/3421654 →

Note that using the gitlab UI to merge does by default not use the commit message format that's common in drupal, while having authors mentioned there or not is being discussed, but having that and the issue number allows to generate release notes with https://drupal-mrn.dev/

I should indeed have squashed it and used the message from the issue here. Normally I always do this, but have forgotten about it this time 😟 Unfortunately I can't git amend and do a force push.

Nice tool by the way!
