fix(deps): Updating some dependencies for making the demo runnable (again)

Update Spring Boot, Java, and docker-compose-rule-junit4 versions in pom.xml.
The Spring Boot parent version has been updated to 2.7.18. Along with that, the Java version has been updated to 17. This necessitates corresponding changes in Maven compiler source and target versions. Also updated docker-compose-rule-junit4 version to 1.9.0 for compatibility with the updated versions.
