  **Added** support for automatically set default network to Ambient workloads if they are added to the Ambient before the network topology is set.
  Before, when you set `topology.istio.io/network` on your Istio root namespace, you need to manually rollout the Ambient workloads to make the network change take effect. 
  Now, the network of Ambient workloads will be automatically updated even if they do not have a network label.
  Note that if your Ztunnel is not in the same network as what you set in the `topology.istio.io/network` label in your Istio root namespace, your Ambient workloads will not be able to communicate with each other.
