[Meta] Switching to Gitlab CI

Note that the community slack #gitlab channel is very active and is also a great place to get help from people.

That's a great tip, thanks @fjgarlin! I added it in the Issue Summary.

Core and contrib made a full split a few weeks ago (they were already almost like separate codebases but still had a few things in common, which were finally split too). Core templates are 100% managed via core and contrib templates are managed via this project, so we should link here only issues about integration for contrib projects in my opinion.

Thanks for clarifying @fjgarlin :) In that case I'll remove it and make the issue title more precise.

This issue can probably be closed now?

Yeah, I think so, we now have +3.5K projects running GitLab CI (https://git.drupalcode.org/search?group_id=2&repository_ref=main&scope=b...)

This has now even passed the usage of DrupalCI ( https://www.drupal.org/project/drupalci/issues/3412417#comment-15410492 → - October 2023).

Any projects wanting help can:
- https://www.drupal.org/docs/develop/git/using-gitlab-to-contribute-to-dr... →
- Go through https://project.pages.drupalcode.org/gitlab_templates/
- Ask for help via the community #gitlab channel
- Create an issue in this queue asking for help

I updated the issue summary to reflect that.

Thanks. Good info in the issue summary

That's great

That sounds great, thanks for the update :)
