[SPARK-51538] Add `spark-connect-server-with-spark-cluster.yaml` example
### What changes were proposed in this pull request?
This PR aims to add an example to launch `Spark Connect Server` pod which
uses the existing `Spark Cluster`.
### Why are the changes needed?
Since `Spark Connect Server` pod is launched outside of `Spark Cluster`, we
can expose the service port more easily.
### Does this PR introduce _any_ user-facing change?
No. This is a new example.
### How was this patch tested?
Manual testing.
Launch `Spark K8s Operator`, `Spark Cluster`, and `Spark Connect Server`
sequentially.
```
$ helm install spark-kubernetes-operator \
https://nightlies.apache.org/spark/charts/spark-kubernetes-operator-0.1.0-SNAPSHOT.tgz
$ kubectl apply -f examples/prod-cluster-with-three-workers.yaml
$ kubectl apply -f examples/spark-connect-server-with-spark-cluster.yaml
```
After exporting the `Spark Master` and `Spark Connect Server` ports,
connect with `pyspark` client.
```
$ bin/pyspark --remote sc://localhost:15002
```
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #169 from dongjoon-hyun/SPARK-51538.
