fix: isBlockActive should use Array.from() (#4662)

Browse Source 
* fix: isBlockActive should use Array.from()

The richtext.tsx example `isBlockActive`  was not working for me in my environtment because `Editor.nodes` returns a Generator, not an Array. So `isBlockActive` always returned false. Wrapping it in `Array.from` fixes the example.

* run prettier
