Change localization branch to release/8.0.1xx temporarily

[carlossanlop]

Similar to the change we did in dotnet/runtime (dotnet/runtime#90812), we need to temporarily switch the OneLocBuild MirrorBranch to point to the release/8.0.1xx branch to ensure all localization changes go there until we ship. This change will be reverted after we ship, so that we point to main again. We need to backport this to the release/8.0.1xx branch as well (like in dotnet/runtime#90813).

/backport to release/8.0.1xx

I doubt the backport GH action is enabled in this repo.

The changes make sense to me, but I don't know how the localizations was working in the branches before, I would wait for approval from @mavasani or @sharwell
