Update cron example with new EventListener prefix.
Update cron example with new EventListener prefix.

The EventListener prefix was updated in https://github.com/tektoncd/triggers/commit/ecd97356c856ad73499fb383ae4ed8010fe48ee0, which broke this example. This updates the service name to match the change.
