Update GORM for org.hibernate:hibernate-core-jakarta:5.6.15.Final

[sdelamo]

see: https://github.com/orgs/grails/discussions/13521

The latest conversations have been for development to begin around org.hibernate:hibernate-core-jakarta:5.6.15.Final and see how well it will play with Spring Framework 6.1.11 and Spring Boot 3.3.1 within GORM for Grails 7. Whatever functions and is the simplest path is likely what will ship in with Grails 7.

Grace has org.hibernate:hibernate-core-jakarta:5.6.15.Final with springBootVersion=3.0.13, springVersion=6.0.22 and groovyVersion=4.0.22
