Fix: use @pytest.mark.stress on test_020 to exclude from PR validation pipeline

- Replace @pytest.mark.stress_threading with @pytest.mark.stress in test_020_multithreaded_stress.py
- Update stress-test-pipeline.yml to use -m stress instead of -m stress_threading
- pytest.ini addopts = -m 'not stress' now covers both test_011 and test_020
