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.

Adds installer/fabro.rb.template and an update-homebrew job that
generates the formula from release artifacts and pushes it to
fabro-sh/homebrew-tap on each tagged release.
