Add failing example from graalpy CI

[LilyFoote]

I saw this failure on #4648 for the pythongraalpy24.0-x64 ubuntu-latest rust-stable build.

  FAILED tests/test_datetime.py::test_datetime_from_timestamp - hypothesis.errors.FlakyFailure: Hypothesis test_datetime_from_timestamp(dt=datetime.datetime(4011, 7, 28, 23, 53, 28, 538099, fold=1)) produces unreliable results: Falsified on the first call but did not on a subsequent one (1 sub-exception)
  Falsifying example: test_datetime_from_timestamp(
      dt=datetime.datetime(4011, 7, 28, 23, 53, 28, 538099, fold=1),
  )

@davidhewitt Is there a way to run the graalpy tests? I tried setting CI-build-full, but that doesn't seem to have done it.

git commit --amend and force push again, the CI doesn't rerun if you just change the label.
