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.
In legacy/trac#30928 (moved), we added a homebrew update to .travis.yml for shellcheck.
legacy/trac#30279 (moved) also uses an updated tor for the IPv6 v3 single onion service job.
This ticket removes that update.
