Fix the port configuration for insecure server

[chandankumar4]

Fixes: https://github.com/numaproj/helm-charts/issues/10

Have verified for below cases:

case 1: With setting server.configs.insecure as "true"

**installing numaflow**
$ helm install numaflow . --set server.configs.insecure="true" --namespace numaflow-system --create-namespace
NAME: numaflow
LAST DEPLOYED: Mon May 20 23:12:46 2024
NAMESPACE: numaflow-system
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
1. Get the application URL by running these commands:
  export POD_NAME=$(kubectl get pods --namespace numaflow-system -l "app.kubernetes.io/name=numaflow-ux" -o jsonpath="{.items[0].metadata.name}")
  export CONTAINER_PORT=$(kubectl get pod --namespace numaflow-system $POD_NAME -o jsonpath="{.spec.containers[0].ports[0].containerPort}")
  kubectl --namespace numaflow-system port-forward $POD_NAME $CONTAINER_PORT
  echo "Visit http://127.0.0.1:$CONTAINER_PORT to use your application"

**Configmap info:**
 $ kubectl get cm -n numaflow-system numaflow-cmd-params-config -o yaml
