Drop old integrations and switch to Jakarta Persistence

[beikov]

To make it easier for newcomers, improve our CI times and also make the lives of the core Blaze-Persistence developers easier, version 2.0 will drop support for old and unsupported integrations.

Blaze-Persistence 2.0 will only support:

• Hibernate ORM 6.2+ and hence Jakarta Persistence 3.1
• Spring Boot 3.1+
• Quarkus 3.2+
• Jakarta EE 10+

In addition to that, support for other libraries will be aligned with the oldest supported version of these main frameworks or if backwards compatible, to the officially community supported version.

@beikov can you ping me whenever the 2.0 branch is somewhat stable?

Then I will update the Querydsl module.

It likely wont be a lot of work, I already use it with the latest Hibernate and Jakarta.

Feel free to disable the maven module for now to get the build to pass :)
