Github workflow: Fix linking error on macOS

 Homebrew has multiple versions of python which occasionally step on
 each other. Add the overwrite flag in the install process to
 explicity oveverwrite old links.

 Additionally add a call to brew upgrade to handle issues where
 new packages require updating already installed ones.
