[SPARK-57789] Update and bundle LICENSE-binary and licenses-binary to describe all bundled libraries

[dongjoon-hyun]

What changes were proposed in this pull request?

This PR updates LICENSE-binary to describe all third-party libraries bundled in the operator
shadow jar, adds the licenses-binary/ directory with the license texts of the non-Apache
components, and bundles them into the jar like Apache Hadoop's hadoop-client-runtime.

• LICENSE-binary: rewritten in Apache Spark's LICENSE-binary format, listing the 170 bundled
  artifacts grouped by license. The list was verified against the actual shadow jar contents.
• licenses-binary/: adds the 11 license texts for the non-Apache-licensed components.
• spark-operator/build.gradle: the shadow jar now ships LICENSE-binary/NOTICE-binary as
  META-INF/LICENSE/META-INF/NOTICE plus META-INF/licenses-binary/, instead of the
  source-release LICENSE/NOTICE.
• .github/.licenserc.yaml: skips the header check for licenses-binary/**.

Why are the changes needed?

LICENSE-binary was a copy of LICENSE and did not enumerate any bundled dependency. Per the
ASF licensing policy, a convenience binary must account for all bundled licenses and include the non-Apache license texts.

Does this PR introduce any user-facing change?

No.

How was this patch tested?

Pass the CIs.

Manually verified that META-INF/LICENSE in the shadow jar is identical to LICENSE-binary, and
that every listed artifact actually has classes in the shadow jar (relocation-aware comparison
against the original jars from Maven Central).

Since we use minimize feature to build uber jar, it becomes a little complicated. I'm rechecking the dependency.
