GitLab's SSH moved to port 22 and sshd to port 2222

GitLab's SSH clone URLs no longer require port 222. This matches the structure used by most GitLab instances. Previous clone URLs (which include port 222) will continue to work for the foreseeable future. The host's SSH port has been changed to 2222 and Ansible will use it automatically. Arch DevOps will also need to: ssh-keygen -R gitlab.archlinux.org Credits go to Kristian for suggesting and implementing this quality-of-life improvement: https://gitlab.archlinux.org/archlinux/infrastructure/-/merge_requests/716
