`qt_no_exception_capture = 0` is not working

I have found that

https://github.com/pytest-dev/pytest-qt/blob/cdad310e88bcabe0cd6eb21843125b43706b54f1/src/pytestqt/exceptions.py#L90-L95

always returns False because disabled is either "0" or "1" (as strings) or Mark(...), depending on whether I use pytest.mark.qt_no_exception_capture or qt_no_exception_capture = 1, all of which evaluate to True.

Then run pip install -e . && pytest -s tests\test_bug.py and see all False.

Start in src/pytestqt/exceptions.py at _is_exception_capture_enabled and reproduce the behavior with the example in tests/test_bug.py. Run pip install -e . && pytest -s tests\test_bug.py, then add regression coverage for the configuration and marker cases so their exception-capture status is evaluated correctly.
