[SPARK-46127][PYTHON][TESTS] Disable pyspark.tests.test_worker.WorkerSegfaultNonDaemonTest.test_python_segfault with Python 3.12

### What changes were proposed in this pull request?

This PR disables `pyspark.tests.test_worker.WorkerSegfaultNonDaemonTest.test_python_segfault` with Python 3.12 for now.

### Why are the changes needed?

This test is flaky, and stops the tests run till the end, e.g., see https://github.com/apache/spark/actions/runs/7006848931/job/19059701743

How `faulthandler` is used is correct, as documented in the standard Python documentation. So I do believe this is a bug from Python 3.12. I will track separately in Python side.

### Does this PR introduce _any_ user-facing change?

No, test-only.

### How was this patch tested?

Manually:

```bash
python/run-tests --python-executable=python3  --testnames 'pyspark.tests.test_worker WorkerSegfaultNonDaemonTest.test_python_segfault'
```

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

No.

Closes apache#44044 from HyukjinKwon/SPARK-46127.
