GH-510 - Upgrade to Spring Boot 3.3 M2.

Explicitly exclude Reactor Core to avoid the Neo4j reactive auto-configuration kicking in, now unconditionally registering a reactive transaction manager causing simple @transactional declarations to break as two transaction manager beans are present.

Also upgrade to Spring Framework 6.1.4 for Javadoc reference.
