ValidatorSupport.getValidators() should return a List<Validator<? super T>> instead of List<Validator<T>>, because PECS.

For instance, if MyEntity implements HasFoo and FooValidator implements Validator<HasFoo>, then MyEntityService can implement getValidators() as:
public List<Validator<? super MyEntity>> getValidators() {
return List.of(new FooValidator());
}
(which makes sense because FooValidator is able to validate any Foo, including my entity)
