[CI][Java] Remove excluded unstable tests when building java-jars.

### Describe the bug, including details regarding any error messages, version, and platform.

When we are builiding java-jars we are currently using the following exclusions:
```
exclude_tests="${exclude_tests}|arrow-acero-asof-join-node-test"
exclude_tests="${exclude_tests}|arrow-acero-hash-join-node-test"
```
We should remove those once: https://github.com/apache/arrow/issues/36482 is solved.

### Component(s)

Continuous Integration, Java

Start by locating the java-jars build configuration that assembles exclude_tests and confirm the two exclusions are still present. Check whether Apache Arrow issue 36482 is resolved, then remove the arrow-acero-asof-join-node-test and arrow-acero-hash-join-node-test exclusions and verify the java-jars build.
