homebrew: refactor release process

What

This MR refactor the homebrew release scripts effectively release the homebrew formula. I use the same scripts used for the rpm and deb packages to create a uniform versioning schema among all our packages.

For example, this is a test release: https://gitlab.com/nomadic-labs/tezos/-/jobs/9517191118
