Subject: [PATCH] [SPARK-36835][BUILD] Enable createDependencyReducedPom for
 Maven shaded plugin

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

Enable `createDependencyReducedPom` for Spark's Maven shaded plugin so that the effective pom won't contain those shaded artifacts such as `org.eclipse.jetty`

### Why are the changes needed?

At the moment, the effective pom leaks transitive dependencies to downstream apps for those shaded artifacts, which potentially will cause issues.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

I manually tested and the `core/dependency-reduced-pom.xml` no longer contains dependencies such as `jetty-XX`.

Closes #34085 from sunchao/SPARK-36835.
