MongoItemReader.setSort() doesn't works without json query string

Bug description
When using MongoItemReader with setQuery(Query), setSort(Map<String, Sort.Direction>), Sort doesn't works.
If you wanna use setSort() method, you should use setQuery(String) method. (If you use MongoItemReaderBuilder, it might be jsonQuery())

Environment
Spring Batch 4.3.5

Steps to reproduce

@Bean
public MongoItemReader<Item> sampleItemReader(MongoTemplate mongoTemplate) {
    HashMap<String, Sort.Direction> sorts = new HashMap<>();
    sorts.put("_id", Sort.Direction.ASC);

    return new MongoItemReaderBuilder<Item>()
                  .saveState(false)
                  .template(mongoTemplate)
                  .collection("items")
                  .targetType(Item.class)
                  .pageSize(50)
                  .query(Query.query(Criteria.where("author").is("minjunkweon")))
                  .sorts(sorts); // Note: It will doesn't works.
                  .build();
}

Expected behavior
I think it should work too. But If Spring Data Query has sorts, I think sorts() method should be ignored. (use Query's sort definition)
If you never mind it, let me create PR about this?

Minimal Complete Reproducible example
Please see Steps to reproduce

Start with the MongoItemReader and MongoItemReaderBuilder entry points described in the reproduction, comparing setQuery(Query) with setQuery(String) or jsonQuery(). Reproduce the sorting case using Query and sorts, then verify that sorting works and that any sort already defined on Query takes precedence or the documented behavior is covered by tests.
