### What type of changes will we make to the documentation?

Showcase

### Affects Version(s)

master,1.11.1

### Improving the documentation

TL;DR — Spark 4 compile support landed in #7256 (v1.10.3 / v1.11.x), but no Spark-4 artifact is published to Maven Central ([https://mvnrepository.com/artifact/org.apache.kyuubi/kyuubi-spark-authz](https://mvnrepository.com/artifact/org.apache.kyuubi/kyuubi-spark-authz)). Requesting it be added to the release matrix.

Use case
We run Spark 4.0 with Ranger-based authz. v1.11.1 builds cleanly from source against Spark 4.0 / Scala 2.13 / Java 21 using -Pspark-4.0, so we're currently building and hosting the jar on an internal repo. A published artifact on Central would let us — and other Spark 4 users — consume it directly.

Ask
Add a Spark 4 variant of kyuubi-spark-authz to the release matrix so future releases publish it to Maven Central. Happy to open a PR if a committer can point me at how the existing Spark 3.5 release is wired.

### Are you willing to submit PR?

- [x] Yes. I would be willing to submit a PR with guidance from the Kyuubi community to improve.
- [ ] No. I cannot submit a PR at this time.

Start by comparing the existing Spark 3.5 release wiring with the Spark 4.0 profile mentioned in #7256 and -Pspark-4.0; locate the release matrix entry that controls kyuubi-spark-authz publication. Done means the Spark 4 variant is included in a release build and published to Maven Central.
