Remove CREATE_BREAKAWAY_FROM_JOB flag
This flag was only needed for older versions of Windows (XP and Vista), where job nesting wasn't supported. We don't support those versions anymore so we can remove it.
GitLab upgrade completed. Current version is 17.8.1: https://about.gitlab.com/releases/2025/01/16/gitlab-17-8-released/
Git-LFS will be deployed on Monday February 10. Our GitLab instance will be interrupted for a few minutes between 1pm and 2pm.
From this date, the quota check will switch to blocking mode. More informations about quotas: https://gitlab.inria.fr/siteadmin/doc/-/wikis/faq#quota-management-policy-to-monitor-disk-space-by-project-on-gitlab
