URL to check view pods permission is not correct

while looking at making clustering work with the operator, I found that https://github.com/jboss-container-images/jboss-eap-modules/blob/5616fe759baeaeba9edb5b56ff6156420467b723/jboss-eap-config-jgroups/added/launch/ha.sh#L42 may not work as expected.

From the doc, the correct param is labelSelector, not labels (https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#list-and-watch-filtering). I run the curl command in my pod terminal and using labels returns all pods in my namespace (and not only the ones matching the selector). Using labelSelector works as expected.

This is minor since we are only interested by the returned HTTP code and not the actual list of pods.
