Possible bug in NOTES.txt

Hi @jfelten-isp, when I deploy this Chart locally in a K3D cluster I am having some issues.

% k3d cluster start
INFO[0000] Starting cluster 'k3s-default'
INFO[0000] Starting Node 'k3d-k3s-default-server-0'
INFO[0000] Starting Node 'k3d-k3s-default-serverlb'
...
% helm repo add keyporttech https://keyporttech.github.io/helm-charts/
% helm install statsd keyporttech/statsd
...
NAME: statsd
LAST DEPLOYED: Thu Feb 11 15:24:36 2021
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
1. Get the application URL by running these commands:
  export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/name=statsd,app.kubernetes.io/instance=statsd" -o jsonpath="{.items[0].metadata.name}")
  echo "Visit http://127.0.0.1:8080 to use your application"
  kubectl --namespace default port-forward $POD_NAME 8080:80

If I follow the guidance

% export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/name=statsd,app.kubernetes.io/instance=statsd" -o jsonpath="{.items[0].metadata.name}")
% kubectl --namespace default port-forward $POD_NAME 8080:80

... then open `http://127.0.0.0:8081

Any ideas how to resolve the above? If you can clarify I would be happy to send a PR to update the documentation. Thank you
