GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
The automatic re-directing of Orbot Top Sites setting of "duckduckgo.com" to httpS://duckduckgo.com doesn't work any longer.
You get to http://duckduckgo.com instead. Bug?
