Rename git master to main
Following tpo/core/team#2 (closed) as a template: let's (finally) do this.
We don't have this problem in the following projects:
- Tor Browser
- Fenix
- Android Components
We should rename the default branch of:
- Tor Browser Build
- RBM
- Torbutton
- Tor Launcher
- Tor Android Service
- Tor Browser Bundle Testsuite
- Tor Browser Spec
