Add macOS to the Github Action

I see you have old versions for macOS: https://github.com/GhostTroops/scan4all/blob/9a9e2d5b40ccb49074bbef3b7826a096102cfca8/Formula.rb#L4

Can you release the latest for macOS? or add Github Action to build for macOS as well?
