Cannot serialize Pageable.unpaged() anymore with Jackson

[balazsmaria]

This fails on main but works on 3.1:

@Slf4j
public class PageableTest {

  @Test
  void test() throws JsonProcessingException {
    var page = new PageImpl<>(List.of(""));
    String valueAsString = new ObjectMapper().writeValueAsString(page);
    log.info("{}", valueAsString);
  }
}

Is this intentional?
Background: this change breaks our controllers with Page types, I'm sure I'm not alone with this use case, see eg. (this well known tutorial site).

On second thought and after looking at PageableHandlerMethodArgumentResolverSupport it makes little sense to pass an Unpaged to the serializer.
