[KYUUBI #5318] Pin maven-source-plugin 3.2.1

### _Why are the changes needed?_

The current maven-source-plugin version(3.3.0) inherits from `org.apache:parent:pom:30`, unfortunately, MSOURCES-121 breaks shaded modules to create source artifacts.

```
[ERROR] We have duplicated artifacts attached.
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-source-plugin:3.3.0:jar-no-fork (attach-sources) on project kyuubi-hive-jdbc-shaded: Presumably you have configured maven-source-plugn to execute twice times in your build. You have to configure a classifier for at least on of them. -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-source-plugin:3.3.0:jar-no-fork (attach-sources) on project kyuubi-hive-jdbc-shaded: Presumably you have configured maven-source-plugn to execute twice times in your build. You have to configure a classifier for at least on of them.
```

We should skip upgrading until MSOURCES-141 gets fixed.

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [x] [Run test](https://kyuubi.readthedocs.io/en/master/contributing/code/testing.html#running-tests) locally before make a pull request

### _Was this patch authored or co-authored using generative AI tooling?_

No.

Closes #5318 from pan3793/mvn-source.
