fix: Use data hooks for FAQ heading synchronization

Updates the `useSyncQuestionHeadingLevels` hook to leverage `@wordpress/data`'s
`useSelect` and `useDispatch` for accessing block editor state and actions.

This removes the need to pass the `blockEditor` object as a prop, improving
the hook's encapsulation and aligning with modern WordPress block editor
development patterns.
