### What changes were proposed in this pull request?
This PR aims to add `submit-spark-connect-server.sh` example to run

Note that there are other ways to launch `SparkConnectServer` and this only
aims to focus on `Spark Standalone` case.
### Why are the changes needed?
1. Install Nightly `Spark Kubernetes Operator` and run a Spark cluster.
```
$ helm install spark-kubernetes-operator \

LAST DEPLOYED: Mon Mar 3 20:55:41 2025
NAMESPACE: default

REVISION: 1
$ kubectl apply -f prod-cluster-with-three-workers.yaml
sparkcluster.spark.apache.org/prod created
```
2. Setup port-forwarding.
```
$ kubectl port-forward svc/prod-master-svc 6066:6066
```
```
$ kubectl port-forward svc/prod-master-svc 6066:6066
```
3. Submit `SparkConnectServer`.
```
$ ./submit-spark-connect-server.sh
{
"action" : "CreateSubmissionResponse",
"message" : "Driver successfully submitted as driver-20250304045839-0000",
"serverSparkVersion" : "4.0.0-preview2",
