Code snippets to update a file in a gitlab group

We need a snippets to do a small update to a file in all the non-archived projects of a GitLab group. Ideally, we want to change VERSION: $CI_COMMIT_SHA to VERSION: commit-$CI_COMMIT_SHORT_SHA in .gitlab-ci.yml. We can simply replace the first occurence.

There is some code already in:

• https://gitlab.teklia.com/infra/devops/-/blob/ml-prod-cmds/devops/mlprod/update.py?ref_type=heads (to do the update)
• https://gitlab.teklia.com/infra/devops/-/blob/ml-prod-cmds/devops/mlprod/init.py?ref_type=heads#L46 (iteration over the projects)
