`enum.Enum.__dir__` docs do not mention enum members in return value

[chgnrdv]

3.12 documentation for enum.Enum.__dir__ says that this method returns "['__class__', '__doc__', '__module__', 'name', 'value'] and any public methods defined on self.__class__", but this is not true, e.g. when using the code provided:

>>> from enum import Enum
>>> from datetime import date
>>> class Weekday(Enum):
...     MONDAY = 1
...     TUESDAY = 2
...     WEDNESDAY = 3
...     THURSDAY = 4
...     FRIDAY = 5
...     SATURDAY = 6
...     SUNDAY = 7
...     @classmethod
...     def today(cls):
...         print('today is %s' % cls(date.today().isoweekday()).name)
... 
>>> dir(Weekday.SATURDAY)
['FRIDAY', 'MONDAY', 'SATURDAY', 'SUNDAY', 'THURSDAY', 'TUESDAY', 'WEDNESDAY', '__class__', '__doc__', '__eq__', '__hash__', '__module__', 'name', 'today', 'value']

Also it seems that test_enum has bug in it, because it doesn't detect the error above if invoked through libregrtest (as ./python -m test test_enum), but direct run of test_enum or doctest on enum documentation fails:

$ ./python -m test.test_enum

This behavior change is probably due to the new Enum implementation in 3.11. Also confirmed on 3.11.

No need to backport to 3.10.
