Homebrew Cask: Google Fonts Versioning

[IlIllIl]

Match Google Fonts version through this JSON:
https://fonts.sandbox.google.com/metadata/versions
This file contains the font version and the commit hash it points to. This means we can handle and update version, url, and sha256 in livecheck. Additionally, the brew audit may need to be skipped as a special case because the url doesn't contain version.
It is useful for upgrading Google Fonts, thus preventing situations where a one-time latest version installation without updates.

@IlIllIl We would review a PR that updates the script to add versioning to the cask files, but the checksums and versioned url may not be necessary as we are using sparse checkouts with a git operation. If you would like to look into this the script that automates the addition, update and removal of Google Fonts is found here - https://github.com/Homebrew/homebrew-cask/blob/main/developer/bin/import_google_fonts
