Ability to add image previews for each style

I agree that solid label descriptions should suffice.

That said, I did open a slightly similar issue: https://www.drupal.org/project/layout_builder_styles/issues/3351372 ✨ Add custom radio button option with visual indicator Active

Perhaps there is an opportunity to collaborate on something here? I don't want to clutter the UI, but some visual indicators can be helpful.
