typing.Protocol in 3.11 needs to be backported

[Gobot1234]

In [6]: @runtime_checkable
 ...: class BaseBadge(Protocol):
 ...: def __init__(self) -> None: ...

In [7]: BaseBadge.__init__
Out[7]: <function typing._no_init_or_replace_init(self, *args, **kwargs)>

This behaviour is not consistent with python 3.11

>>> from typing import *
>>> @runtime_checkable
... class BaseBadge(Protocol):
... def __init__(self) -> None: ...
... 
>>> BaseBadge.__init__
<function BaseBadge.__init__ at 0x104f249a0>

This may have made me slightly concerned I was loosing my sanity in a subclass today 😀

This is python/cpython#31628, PR welcome.

Heya, I would also note that there will hopefully be another change coming, I guess in 3.12, that would be great to have backported: python/cpython#102433
