New Baseline: Spring Boot 3 and Java 17

* Minimum supported version of Java is now 17
* Minimum supported version of Spring Boot is now 3.2

Spring Boot versions older than 3.2 reached EOL and will not receive any further support nor security patches. It would be a security risk to continue using EOL-ed versions in this LangChain4j project.
