Social default branch has been changed to "main"

[Christopher Davis <christopherdavis gnome org>]

Social (https://gitlab.gnome.org/World/Social) is moving away from using the "master" branch.

I have created the new "main" branch already and have set it as the default. Before I delete the

master branch, I would like to get the translations module pointed to "main" instead of "master".
