Fix pytest-raises-too-broad (PT011) to flag pytest.raises call with keyword expected_exception

[harupy]

Summary

pytest-raises-too-broad (PT011) should be raised when expected_exception is provided as a keyword argument.

def test_foo():
    with pytest.raises(ValueError):  # raises PT011
        raise ValueError("Can't divide 1 by 0")

    # This is minor but a valid pytest.raises call
    with pytest.raises(expected_exception=ValueError):  # doesn't raise PT011 but should
        raise ValueError("Can't divide 1 by 0")
