Have both master and main branches work at the same time, without breaking?

Feature Description

Some CI/CD workflows break when someone renames master branch to main.

What if there would be no need to change branch names, both "master" and "main" would work when there is one of those, and at visible web interfaces would visibly just show text "main", not "master"? This way, there would be no need to manually rename branches, and all repos would be "main" compliant by default. That change would only need to be done to git hosting software like GitHub, and it would save the world from a lot of breakages.

I also asked about this from Gitea go-gitea/gitea#18733

Both ways:

1. Renaming master to main: https://github.com/github/renaming .If master is renamed to main, it would be better that using master would still work.
2. If someone has not yet renamed master to main, cloning main would be good to work also
3. Web UI could always show that branch name is main. So nobody would have to make manual renames of branches.
