【Pybind11】：没有正确判断静态成员变量，自然也没有正确处理相关转换

class Pybind11DefaultStaticMemberVariableTranslator(
    common_translators.DefaultMemberVariableTranslator
):
    ...

    def condition(self, member_variable: cursors.MemberVariable) -> bool:
        return (
            super().condition(member_variable)
            and member_variable.is_public
            and member_variable.is_static
        )

这并不能正确判断静态成员变量。
