The org.keycloak:keycloak-services dependency and the org.keycloak:keycloak dependency should be updated to the latest versions.

Note: newer version is available for keycloak-services, however, that is build using Java 17, which causes any tests with previous JDK version (i.e. Java 11) to fail. Since this dependency is only used for tests, this is not updated to the latest version at this moment. 

Upgrade to 25.0.2 for keycloak-core requires updating io.restassured.
