Add support for alternative Google Font source in the Typography panel

Is your feature request related to a problem? Please describe.
There's a couple sites that provide Google Fonts, but meet GDPR requirements -- we should add support for fonts loaded from those URLs as an alternative.

The URLs are:

• https://fonts.bunny.net/
• https://github.com/coollabsio/fonts

Additional context
If they seem to work well, it would be good to update the Design Wizard to use updated URLs for any of the fonts that are available from both Google and a third-party site.
