[SPARK-53828] Exclude org/apache/spark/ui/static/** from Spark operator jar

### What changes were proposed in this pull request?

This PR aims to exclude `org/apache/spark/ui/static/**` pattern from Spark operator jar.

### Why are the changes needed?

Apache Spark K8s operator doesn't require `Apache Spark` static web resources. We had better clean them up.

**BEFORE (Apache Spark K8s Operator 0.5.0)**
