How to preserve refspec to patches and branches after the repo renamed 'master' to 'main'

[Nirmal4G]

For all those who can't pull master, it has renamed to main.

To preserve refspec to patches and branches, just changing the heads/master to heads/main should work.

[remote "origin"]
	url = https://github.com/dotnet/runtime
-	fetch = +refs/heads/master:refs/remotes/origin/master
+	fetch = +refs/heads/main:refs/remotes/origin/master
	tagopt = --no-tags
[branch "master"]
	remote = origin
-	merge = refs/heads/master
+	merge = refs/heads/main

Putting this out there, if anyone else facing similar issue with git.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Alternative to #48357. For those who cannot change the default branch for obvious 😉 reasons.

Closing in favor of #48357
