Give developers the option to disable Google fonts for Web Stories

[adamdunnage]

Feature Description

As raised in the support forum, it would be useful for some users of the plugin to be able to disable Google fonts for their Web Stories.

This could be provided in the form of documentation for developers who should be made aware that this be carried out at their own risk.

Adding a UI option for this would be considered high risk for users as it could potentially break templates and existing stories so adding this as documentation for developers is the preferred approach.
