Update getting-started.adoc - set zookeeper cli port

[csautter]

In my case the default port was not correct, leading to an error:

 % kubectl exec -i -t simple-zk-server-primary-0 -- bin/zkCli.sh                        
Defaulted container "zookeeper" out of: zookeeper, prepare (init)

Thanks, good catch! I don't think we need to complicate the surrounding text, but we should definitely be aware of this. ..especially since this affects our default configuration.
