Subject: [PATCH] ci: publish fabro-beta Homebrew formula on pre-release tags

Adds a sibling Homebrew formula so users can opt into pre-releases with
`brew install fabro-sh/tap/fabro-beta`. Pre-release tags (v*-*) update
Formula/fabro-beta.rb in the tap; stable tags still only touch
Formula/fabro.rb. The two formulae declare conflicts_with each other
since they both install the fabro binary.
