Thanks for the contribution. Note that dependency updates are usually something we have to do ourselves, as we have to coordinate with the downstream portfolio regarding their plans to upgrade, too.

For reference for others: also note that you can already use Hibernate 6.2 with an existing boot application by simply configuring hibernate.version to 6.2.0.Final. What's suggested here is upgrading Spring Data's build to Hibernate 6.2, which, given we primarily target JPA in our production code, is more of a testing topic than a "can Spring Data JPA work with Hibernate 6.2".

@odrotbohm I think this issue needs to be tagged with milestone (3.1 RC1 (2023.0.0)), right?

We're not done yet. There are a couple of tests failing after the upgrade. Investigating.
