Consider enabling Custom Domains for GitLab pages

Linus, GK, and I are working on a small community day event (announced various places now) later this year, and we have a litle F.A.Q page with some information on the venue and so on. We wanted to avoid Github and Gitlab.com (since they block Tor), so gitlab.torproject.org seemed like a good option as we all spend a lot of time on here every day.

I tried to enable pages with custom domains as per the instructions in https://docs.gitlab.com/user/project/pages/custom_domains_ssl_tls_certification/#steps

When I went into my Gitlab project, looked at Deploy, then Pages, it said:

Support for domains and certificates is disabled. Ask your GitLab administrator to enable it.

Is this something we want to enable down the line?

(There is no urgency to this at all from my side, and this is not a blocker for anything TPI related)
