release: update Homebrew tap (#1374)

GCM has migrated from the `microsoft/homebrew-git` tap to the
`Homebrew/homebrew-cask` tap. This change contains two related updates:

1. The `release-homebrew` workflow now publishes to
`Homebrew/homebrew-cask`.
2. The docs now instruct users to install from the new tap.

The workflow updates were [tested in my
fork](https://github.com/ldennington/homebrew-cask/pull/5/files). There
is also a [corresponding PR in
`microsoft/homebrew-git`](microsoft/homebrew-git#73)
that will ensure users currently set up to upgrade from the
`microsoft/homebrew-git` tap will be automatically re-directed to
`Homebrew/homebrew-cask`.
