Update `validate_abstract_methods` in `test_collections.py`
The test for missing abstract methods in `validate_abstract_methods` incorrectly attempted to instantiate the generated class `C` with an argument (`C(name)`), which always raises a `TypeError: C() takes no arguments`. Although the test originally passes, it passes for the wrong reason.
This change makes the test correctly validate the enforcement of abstract methods in ABCs.

The test suite fetches the C recursion limit from the _testcapi
extension module. Test extension modules can be disabled using the
--disable-test-modules configure option.
This PR makes some minor linting adjustments to the Lib/test module
caught by [ruff](https://github.com/charliermarsh/ruff). The adjustments
are all related to the `F541 f-string without any placeholders` issue.

* bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path
* Add News entry
* fixup! bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path
* Check for tuple in the __get__ of the new descriptor and don't cache the descriptor itself
* Don't inherit from property. Implement GC methods to handle __doc__
* Add a test for the docstring substitution in descriptors
* Update NEWS entry to reflect time against 3.7 branch
* Simplify implementation with argument clinic, better error messages, only __new__
* Use positional-only parameters for the __new__
* Use PyTuple_GET_SIZE and PyTuple_GET_ITEM to tighter the implementation of tuplegetterdescr_get
* Implement __set__ to make tuplegetter a data descriptor
* Use Py_INCREF now that we inline PyTuple_GetItem
* Apply the valid_index() function, saving one test
* Move Py_None test out of the critical path.
