LGTM, one question, SPARK-42769 is only available since Spark 3.5, do we need to write something in docs for these requirements? |

Not necessary, this PR can also work with any spark version that supports spark on kubernetes. SPARK-42769 is only for executors to connect to driver via IP. |

…//{{SPARK_DRIVER_POD_IP}}:{{SPARK_UI_PORT}}`
### Why are the changes needed?
We are using [virtual-kubelet](https://github.com/virtual-kubelet/virtual-kubelet) for spark on kubernetes, and spark kubernetes pods would be allocated across kubernetes clusters.
And we use the driver POD ip as driver host, see apache/spark#40392, which is supported since spark-3.5.
The kubernetes context and namespace are virtual and we can not build the app URL by spark driver svc.
And the spark driver pod IP is accessible for our use case, so raise this PR to build the spark app url by spark driver pod id and spark ui port.
### How was this patch tested?
UT.
