Investigate providing a nicer fat jar for use with WildFly #2
Description
We are adding quite a lot of dependencies in the test https://github.com/kabir/a2a-java-sdk-server-jakarta/blob/main/src/test/java/org/wildfly/extras/a2a/server/apps/jakarta/JakartaA2AServerTest.java#L37-L50
Although some of these are needed to run the Arquillian test in-container. Others like Jackson should be provided by the server.
