Spring Upgrade to Hibernate ORM 7.1

After the initial upgrade to Hibernate ORM 7.0 in #33750, let's upgrade to the just released Hibernate ORM 7.1 for Spring Framework 7.0 M8 now.

As far as we foresee, Spring Framework 7.0 GA will ship with a Hibernate ORM 7.1 baseline, aiming to support Hibernate ORM 7.1+ going forward.
