Subject: [PATCH] bump-cask-pr: ensure new_cask has a url

We sometimes see errors like "attempted to use a `Downloadable`
without a URL!" in the homebrew/cask autobump workflow log because
`bump-cask-pr` can simulate Linux even if a cask doesn't support it,
leading to this error. This is something that should be resolved in
the future once I finally wrap up my related work to detect OS/arch
requirements but this adds a simple guard to address this in the
interim time.
