[SPARK-57794] Exclude 3rd party Maven metadata from shadow jar
### What changes were proposed in this pull request?
This PR excludes 3rd party Maven metadata (`META-INF/maven/**`) from the
`spark-operator` shadow jar.
### Why are the changes needed?
`minimize()` strips unreachable classes but leaves the matching
`pom.properties`/`pom.xml` behind, so orphaned Maven metadata remains for
fully-removed dependencies. These files are build-time only and serve no
runtime purpose.
For the record, we provide SBOM for trace-ability.
- #332
### Does this PR introduce _any_ user-facing change?
