Describe the Issue
Keycloak 25 completed transitioning away from Resteasy core. As a result of this transition, the class org.keycloak.common.util.ResteasyProvider was removed.

Expected Behavior
Resteasy3Provider, which implements org.keycloak.common.util.ResteasyProvider, should be modified or replaced to ensure compatibility with the updated Keycloak version.
