[3.12] pythongh-87969: Align docs and docstrings with implementation for ctypes' [w]string_at() (pythonGH-25384) (pythonGH-118046)

pythongh-87969: Align docs and docstrings with implementation for ctypes' [w]string_at() (pythonGH-25384)

The implementation uses 'ptr' for the name of the first parameter of
ctypes.string_at() and ctypes.wstring_at(). Align docs and docstrings
with the naming used in the implementation.

(cherry picked from commit 81a926b)
