Rename master branch to main

[bampakoa]

Hey all 👋

We are currently in the process of renaming the master branch into main. This change will not have any effects on opened PRs but if you have forked the repository you should update your local environment to match the new name.

For guidance on how to update your local branch, check out this guide https://git-scm.com/book/en/v2/Git-Branching-Branch-Management.

Thanks!
