Update to silence the warning

[Daniele-Tentoni]

Hello, before all, thank you for the useful action. I've noticed this warning in log of my runs:

hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint: 
hint: 	git config --global init.defaultBranch <name>
hint: 
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint: 
hint: 	git branch -m <name>

Can I prepare a pull request to silence this warning? My proposal is to call the default branch not master, but main, like Github is already suggesting.

Yeah, go ahead
