Add missing PyDoc_STR calls

[sobolevn]

PR #108811 by @Gobot1234 made me curios to grep other possible places where this problem exists. I found some! 👍

Merged, thanks. I listed modified files in the commit message.

Sorry for only checking this now but it seems like some were still missed with PyMemberDefs e.g. here

cpython/Modules/_json.c

Lines 31 to 36 in 5eec58a

	{"strict", Py_T_BOOL, offsetof(PyScannerObject, strict), Py_READONLY, "strict"},
	{"object_hook", _Py_T_OBJECT, offsetof(PyScannerObject, object_hook), Py_READONLY, "object_hook"},
	{"object_pairs_hook", _Py_T_OBJECT, offsetof(PyScannerObject, object_pairs_hook), Py_READONLY},
	{"parse_float", _Py_T_OBJECT, offsetof(PyScannerObject, parse_float), Py_READONLY, "parse_float"},
	{"parse_int", _Py_T_OBJECT, offsetof(PyScannerObject, parse_int), Py_READONLY, "parse_int"},
	{"parse_constant", _Py_T_OBJECT, offsetof(PyScannerObject, parse_constant), Py_READONLY, "parse_constant"},

I can't see any that were missed on PyMethodDefs at a cursory glance but that might be worth looking through as well

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

@Gobot1234 you are right once again:

>>> import json
>>> json.JSONDecoder().scan_once.__class__.object_hook.__doc__
'object_hook'

would you like to make a PR? :)
