[HyukjinKwon]

What changes were proposed in this pull request?

This PR proposes to exclude unittest-xml-reporting in Python 3.12 image

Why are the changes needed?

unittest-xml-reporting seems not supporting, and this seems hiding the real error:

  File "/__w/spark/spark/python/pyspark/streaming/tests/test_kinesis.py", line 118, in <module>
    unittest.main(testRunner=testRunner, verbosity=2)
  File "/usr/lib/python3.12/unittest/main.py", line 105, in __init__
    self.runTests()

    self.result = testRunner.run(self.test)

AttributeError: '_XMLTestResult' object has no attribute 'start_time'. Did you mean: 'stop_time'?

This is optional dependency in testing so we can exclude this (see https://github.com/apache/spark/actions/runs/7462843546/job/20306214215)
