Make `main` the new default branch on gitweb for various repos
In tpo/applications/tor-browser#41321 (closed) we removed the master
on various repositories, after replacing it with the main
branch.
However for some of those repositories, gitweb doesn't know that the main
is the new default branch and use some random other branch instead. For example:
- https://gitweb.torproject.org/builders/tor-browser-build.git/
- https://gitweb.torproject.org/torbutton.git/
The list of repositories that had their master
branch removed is:
- builders/tor-browser-build
- builders/rbm
- torbutton
- tor-launcher
- tor-android-service
- tor-browser-bundle-testsuite
- tor-browser-spec
