Use a working setup-ruby action on Windows to get CI green

New packages with ucrt64 gcc chain were uploaded to
https://github.com/ruby/setup-msys2-gcc/releases/tag/msys2-gcc-pkgs very
recently and they seem to have broken extension compilation on Windows.

Apparently recent GCC issues have led to a rewrite of the
ruby/setup-ruby action on Windows, and the rewrite does have any issues
and it's also dramatically faster.

So switch to that for now to get our CI back to green.
