Helm deployment note includes faulty code

[neischlah]

Describe the bug

After running helm install, I get instructions on how to find the URLs of the planes:

1. Get the control plane URL by running these commands:

  export NODE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].nodePort}" services tx-plato)
  export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")
  echo http://$NODE_IP:$NODE_PORT

2. Get the data plane URL by running these commands:

  export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/name=tractusx-connector,app.kubernetes.io/instance=tx-plato" -o jsonpath="{.items[0].metadata.name}")
  export CONTAINER_PORT=$(kubectl get pod --namespace default $POD_NAME -o jsonpath="{.spec.containers[0].ports[0].containerPort}")
  echo "Visit http://127.0.0.1:8080 to use your application"
  kubectl --namespace default port-forward $POD_NAME 8080:$CONTAINER_PORT

The first command fails because there's no service called tx-plato (probably needs to be tx-plato-controlplane?).
The second command fails because jsonpath is incompatible.

To Reproduce

1. Follow the example
2. Run the scripts printed in step 3 after running helm install
