froala/ember-froala-editor

Updates to support Froala Editor v3 along with moving this addon forward to use Octane Edition features, specifically Glimmer Components. Checkout "Upgrading from 2.x" in the README for details, but here are some highlights;

1. Glimmer Components! From {{froala-editor this.content}} to <FroalaEditor @content={{this.content}} />
2. @content must be a SafeString
3. Event callbacks now get the editor instance instead of the component instance as the first arg
4. Call Froala Editor methods directly on the editor instance, no more await component.method()!

This beta only supports 3.13+! However, once a setComponentTemplate() polyfill is ready it should support back to 2.18. TBD though.
