SpringBoot Avoid using Wildly 25.0.0.Final as it rejects all requests that use basic auth

https://issues.redhat.com/browse/WFLY-15478

We use the latest tag of the jboss/wildfly Docker image which currently points to 25.0.0.Final. We need to drop back to Wildfly 24 so that our deployments tests, which now make use of basic auth, pass on Wildfly.
