- This is needed for https://github.com/Homebrew/brew/pull/13603 because `Homebrew/homebrew-versions` is deprecated (legitimately), but `OFFICIAL_CASK_TAPS` spits out `versions` as a repo, which could then be interpreted as `Homebrew/versions` rather than `Homebrew/cask-versions` which it actually is.
