Rename default branch to main

[adalinesimonian]

Per GitHub guidance and in the spirit of other changes in stylelint to remove racist language, we should rename the default branch to main. There would be little to no impact as a result of the switch thanks to changes made by GitHub. The only things we'd need to do are:

• Change the default branch name in the repository settings
• Update CI workflows to refer to the correct branch name
• Rename the branch locally and update refs:

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

That's it! Simple and straightforward as can be.

Ha, I was just looking at this at the same time, happy to do that now if you want

It would also be good to do this for the entire @stylelint org, maybe for the rest of the project after v14 is released

That'd be great, thank you!

Absolutely. Should we create an issue to track the org-wide change on the main repository so that we don't forget about it?

Done, the new default branch is main

Thanks! I'll update the workflows.

Pretty neat, Dependabot PRs auto updated the branch to main

All done!
