Question, Bug, or Feature?:

gh is currently being installed using the homebrew formula github/gh/gh

https://github.com/actions/virtual-environments/blob/7fe98f7934a70fc53b394f3f494ae6a25d6bedf2/images/macos/provision/core/commonutils.sh#L22

That formula name is outdated since gh got moved into homebrew core formulae (https://github.com/Homebrew/homebrew-core/blob/38d4781f10b61240c109ad08c4824e1c01f7ca82/Formula/gh.rb). It is now recommend it be installed using just the gh formula name. Can we update the installer script to use the new formula name?
