[ANN] Default branch rename from 'master' to 'main'

[Aleksander Morgado]

Hey all,

As part of https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/issues/77
and https://gitlab.freedesktop.org/mobile-broadband/libqrtr-glib/-/issues/3,
I've created a new "main" branch as a copy of "master" both both
libqmi and libqrtr-glib, and I'll
remove the "master" branches sometime in the next few weeks.

The new "main" branch is already the default one in the repos, so all
MRs will be against that branch from now on.

If you have a local clone of the repositories, please rename your
local branches as well and point it to the new default branches in
each of the remotes:

$ git checkout master
$ git branch -m master main
$ git fetch
$ git branch --unset-upstream
$ git branch -u origin/main
