This commit ensures that derived types correctly inherit the unchecked_union pragma/aspect in Ada. This means that if a parent type is declared as an unchecked_union, derived types will also inherit this property. This change maintains consistency and avoids unexpected behavior when working with derived types and unchecked unions.
