GitLab Pages offering only TLSv1.3

It seems GitLab Pages is only offering TLSv1.3, according to testssl.sh.

I found this when trying to have feed validators examine https://tpo.pages.torproject.net/web/blog/feed.xml, because my TT-RSS client was unable to add it and I wasn't able to figure out why.

The W3C validator worked but rssboard.com failed with message Server returned [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:727) and tt-rss.org also failed to retrieve the feed.

# testssl -p https://tpo.pages.torproject.net/web/blog/feed.xml
