`D102` - Don't enforce docstrings on `__new__` and `__call__`

re-raising https://github.com/PyCQA/pydocstyle/issues/515 here:

> This should be considered a magic method (controlled by `D105`), or at least have a different error code (which may be `D107` together with `__init__` or even a new one).

Start by tracing Ruff's D102 rule handling and compare it with the linked pydocstyle issue 515. Determine the intended relationship among D102, D105, and D107, then update the relevant behavior and tests so __new__ and __call__ are no longer incorrectly required to have docstrings.
