Support Spring Boot 3.x and Java 17

[slgobinath]

Thanks to @pramoth for this library and @mdillenk for the attempt to migrate to Spring Boot 3.x
The PR #31 works but some changes in the H2 database cause most unit tests to fail. I have fixed the test configurations to get all tests pass successfully.

I'd highly appreciate it if you could release the changes to a new version.

@pramoth this PR, would be amazing if it was merged. Would save so much time to finding another substitute!

@pramoth could you please merge the request if all the requirements covered

Really sad that one can't open their project to new contributors in a save way... @pramoth seems to have moved on, but we'd love to use his legacy...

[tnbossi123]

@slgobinath Could you create a repo with your merged code? So we could use your changes, it does not seem that @pramoth is active longer.

[mdillenk]

Being under the gun at the time I just built and released the project in our nexus server and had our projects depend on that internal dependency going forward.

Hi @tnbossi123 ,
Here's the repo with the changes https://github.com/slgobinath/specification-with-projection/tree/feature-spring-boot-3 but unfortunately I don't have time to maintain it as a fork.

I also moved to Quarkus with QueryDSL so I no longer depend on this library.
