Rename default branch "master" to "main"

[ciozi137]

@Monkeymerlot the default branch is now main https://github.com/github/renaming. Run the following commands to update your local repository:

git fetch
git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

I did this but I had already updated the repository in github desktop so I just deleted the master branch after switching to main locally.
