Adjust the expected string to match Python 3.11+ changed output

[befeleme]

Subject: With Python 3.13.0a2 'test_autodoc_default_options' started failing. It's because Python 3.13.0a2 has changed the __doc__ and __weakref__ docstrings, see: python/cpython#112266

Is it necessary to differentiate the asserted contents? What if we ditched the (if defined) part (always)?

[befeleme]

Since actual is a list of strings, the change of even a single character in the expected output will result in the false-y assertion. The below could work but its readability is quite worse:

assert any('      list of weak references to the object' in output_part for output_part in actual)

[hroncok]

Oh, I thought actual is a string and we are checking a substring here. Never mind me then.

[befeleme]

...or I could join actual to achieve a single string and use in operator without more hassle.

Looks good!

I didn't spot this PR and opened a fairly-similar one this week: #11793

In fact #11793 is better, because in the latest version the condition is improved (0b55aae).

Closed by #11793.
