hellofromTonya 87aa505a94 Editor: Fix error handling of converting classic to block menus.
Fixes the error handling for when `WP_Classic_To_Block_Menu_Converter::convert()` returns an instance of `WP_Error`. `WP_Navigation_Fallback::create_classic_menu_fallback()` now checks for `is_wp_error()` and if `true`, returns the error. And the `@return` type is updated to `string|WP_Error`.

Also includes a fix in the return type in `WP_Classic_To_Block_Menu_Converter::convert()` to return an empty string instead of an array instead, i.e. when bailing out for no menu items returned by `wp_get_nav_menu_items()`. The return type is clearly documented as a `string`.

Follow-up to [56052].
