Bug report

Bug description:

AsyncIterator was removed from _PROTO_ALLOWLIST by #15647, without any discussion. It looks like an accident to me.

from typing import AsyncIterator, Protocol
class MyProto(AsyncIterator, Protocol): ...

result:

TypeError: Protocols can only inherit from other protocols, got <class 'collections.abc.AsyncIterator'>

CPython versions tested on:

3.12

Operating systems tested on:

macOS
