Tests failing if build within a Python 3.13 environment

[tijuca]

The tests are failing if autodocsumm is getting build and tested within a Python 3.13 environment. The failure is looking always the same.

self = <autodocsumm.NoDataDataDocumenter object at 0x7f4bb1b73e70>, args = ()
kwargs = {}, content = 'both'
docstrings = ["str(object='') -> str\nstr(bytes_or_buffer[, encoding[, errors]]) -> str\n\nCreate a new string object from the give...ined)\nor repr(object).\nencoding defaults to 'utf-8'.\nerrors defaults to 'strict'.\nThe type of the None singleton."]
docstring = "str(object='') -> str\nstr(bytes_or_buffer[, encoding[, errors]]) -> str\n\nCreate a new string object from the given...fined)\nor repr(object).\nencoding defaults to 'utf-8'.\nerrors defaults to 'strict'.\nThe type of the None singleton."
calldocstring = 'The type of the None singleton.', doc = []

    def get_doc(self, *args, **kwargs):
        """Reimplemented  to include data from the call method"""
        content = self.env.config.autodata_content
        if content not in ('both', 'call') or not self.get_attr(
                self.get_attr(self.object, '__call__', None), '__doc__'):
            return super(CallableDataDocumenter, self).get_doc(
                *args, **kwargs
            )
    
        # for classes, what the "docstring" is can be controlled via a
        # config value; the default is both docstrings
        docstrings = []
        if content != 'call':
            docstring = self.get_attr(self.object, '__doc__', None)
            docstrings = [docstring + '\n'] if docstring else []
        calldocstring = self.get_attr(
            self.get_attr(self.object, '__call__', None), '__doc__')
        if docstrings:
            docstrings[0] += calldocstring
        else:
            docstrings.append(calldocstring + '\n')
    
        doc = []
        for docstring in docstrings:
            if not isinstance(docstring, str):
                docstring = force_decode(docstring, encoding)
>           doc.append(prepare_docstring(docstring, ignore))
E           NameError: name 'ignore' is not defined

autodocsumm/__init__.py:459: NameError

This is happen as the used variable ignore is never getting something assigned to in this function within autodocsumm/init.py.

Simply removing the variable is making the tests running successfully again in Python 3.12 and 3.13.

This was already fixed differently in ec89d70.
