[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

Comece localizando a configuração de build do java-jars que monta exclude_tests e confirme que as duas exclusões ainda estão presentes. Verifique se o Apache Arrow issue 36482 foi resolvido; em seguida, remova as exclusões arrow-acero-asof-join-node-test e arrow-acero-hash-join-node-test e verifique o build do java-jars.
