Fix gitlab.archlinux.org IPv6
IPv6 on gitlab.archlinux.org broke suddenly. Franky, I got zero clues as to what's going on. I tripplechecked Hetzner and we're using an IPv6 in the allotted subnet.
I did some research here: https://gitlab.archlinux.org/archlinux/infrastructure/-/snippets/3
I'm almost ready to call Hetzner on this but would appreciate it if one of you guys could take a peek.
