More detail for test and running the project

[Kaaveh]

For running the tests, I faced some challenges such as setting the correct JDK version, installing the kotest plugin installing docker, and docker-compose. It would be helpful to include these details in the contribution guide.

Yes, great idea!

But actually.. I think that "the correct JDK version" is a bug in Gradle, it should work on any 11+ JDK. I think there is something wrong with my sourceCompatibility and targetCompatibility 🤔

Oh, got it! It forced me to bump the JDK version from 18 to 19.
