Fix handling of @Id property in Java records

[sothawo]

spring-data-commons introduced the PersistentProperty.isReadable() method in spring-projects/spring-data-commons#2915, a method that SimpleElasticsearchPersistentProperty has had for years and that is now calling the new base implementation. This broke handling of Java record classes in so far as that the @Id annotated property of a record could not be set anymore after storing an entity in Elasticsearch while having the id autogenerated.
