Subject: [PATCH] Update documentation for repository `Pageable` and `Sort`
 arguments.

Replace outdated `null` acceptance for `Pageable` with `Pageable.unpaged()`
 `QueryByExampleExecutor#findAll(Example<S> example, Pageable pageable)` should does not accept null values since there is `Pageable.unpaged()`. Furthermore, the same applies to `PagingAndSortingRepository#findAll(Pageable pageable)`.

Related ticket: spring-projects/spring-data-jpa/issues/2464
Closes #2574
