Deal with ActiveMQ client moving to JMS 2.0 API, releasing both javax.jms and jakarta.jms variants

Starting with activemq-client 5.18.0, JMS 2.0 interface library is required on the classpath.

Since we must maintain compatibility with what Red Hat releases in https://maven.repository.redhat.com/ga/org/apache/activemq/activemq-client/, which seems to be the 5.11.0 version, it seems best to stick to the latest JMS 1.1 and stop following upstream upgrades, unless anything changes.
