[AURON #2407] [BUILD] Fix the invalid Spark 4.1 Docker build example. (#2408)

### Which issue does this PR close?

Closes #2407

### Rationale for this change

The Docker build example generated by `auron-build.sh --help` used Spark
4.1 together with the `centos7` image.

The `centos7` image only provides JDK 8, while Spark 4.x requires JDK 17
or later. The example also enabled Iceberg and Hudi for Spark versions
with which those integrations are not compatible.

As a result, users following the documented example encountered Java
version or integration compatibility errors before completing the build.

### What changes are included in this PR?

- Replace the single Docker build example with explicit examples for
  Spark 3.5, Spark 4.0, and Spark 4.1.
- Use the `rockylinux8` image for these examples because it supports the
  JDK selection required by Spark 4.x.
- Use Scala 2.12 for Spark 3.5 and Scala 2.13 for Spark 4.x.
- Include only compatible third-party integrations in each example:
  - Spark 3.5 includes Iceberg 1.10.1 and Hudi 0.15.
  - Spark 4.0 includes Iceberg 1.10.1 but excludes Hudi.
  - Spark 4.1 excludes both Iceberg and Hudi.
- Add a build compatibility matrix to `CONTRIBUTING.md`.
- Document the Spark, Scala, JDK, Docker image, Flink, Celeborn,
  Uniffle, Paimon, Iceberg, and Hudi combinations.
- Update the existing Docker build example in `CONTRIBUTING.md` to use
  `rockylinux8`.
- Document that the compatibility matrix and Shell help examples should
  be updated together.

### Are there any user-facing changes?

Yes.

The help output now provides separate Docker build examples for Spark
3.5, Spark 4.0, and Spark 4.1. Each example uses an appropriate Scala,
JDK, Docker image, and third-party integration combination.

Contributors can also consult the compatibility matrix in
`CONTRIBUTING.md` before selecting build arguments.
