Upgrade to Hibernate 6.1.1.Final

This commit makes the following potentially breaking changes:

- Dependency management for modules that do not exist in Hibernate
  6.1 has been removed.
- Hibernate's modules are now in the org.hibernate.orm group. Users
  not using the starter or using modules that are not in the starter
  will have to update their build configuration accordingly.
- spring.jpa.hibernate.use-new-id-generator-mappings has been removed
  as Hibernate no longer supports switching back to the old ID
  generator mappings.
