Describe the bug
Ops agent documentation here https://cloud.google.com/monitoring/agent/ops-agent/third-party/activemq advertises that ActiveMQ integration works with ActiveMQ Artemis 2.x brokers however it doesn't work. JMX metric keys have different format in Artemis so they are not returned to monitoring.

To Reproduce
Steps to reproduce the behavior:

1. Start a GCE VM with image 'rocky-linux-9-v20240515'
2. Install Ops Agent version 'google-cloud-ops-agent-2.52.0-1.el9.x86_64.rpm'
3. Install Artemis broker and enable JMX connector in management.xml
4. Customize the agent with configuration and restart the agent

metrics:
  receivers:
    activemq:
      type: activemq
      endpoint: localhost:1099
      collection_interval: 15s
      username: artemis
      password: artemis
  service:
    pipelines:
      activemq:
        receivers:
          - activemq

4. netstat -an |grep LISTEN shows that the agent connected to JMX management endpoint, but not metrics are gathered.

Expected behavior
ActiveMQ integration should work with ActiveMQ Artemis or documentation should be adjusted to remove Artemis from supported app list.

Additional context
Using JVM ops agent integration on the same Artemis installation works, so this is not the issue with Artemis or JMX configuration.
