hellofromTonya 9aba2584bb Themes: Hide "Live Preview" button for FSE block themes.
Currently, the Site Editor does not have a live preview feature for non-activated block themes.

This commit is a stop-gate to remove the "Live Preview" button for those themes. It avoids confusing users and avoiding a notification message that doesn't make sense.
