Default to branch name main rather than master #5617
Description
Describe the bug
The documents reference a default branch master; this should be changed to main if possible, especially seeing as the Netlify deployment documents seem to encourage that too, and github's changing its default to main as well.
To Reproduce
- https://www.netlifycms.org/docs/add-to-your-site/#backend
- See comment
branch: master # Branch to update (optional; defaults to master)
Expected behavior
I'd expect the branch to default to main, or at least the documentation to acknowledge that's becoming the new default in most places.
