rubocops/uses_from_macos: remove versioned aliases.

It makes more sense to use the unversioned formulae with `uses_from_macos`
because macOS isn't shipping multiple versions of this.

If you wish to e.g. pin to a specific version you can do that by specifying the
dependency directly in an `os_linux` block.
