Wrong return type annotathion for json of WSMessage in http_websocket.py

[olned]

The json method of the WSMessage class returns parsed JSON data but declared as return None.

aio-libs/aiohttp/http_websocket.py

Line 86

85    def json(self, *,  # type: ignore
86             loads: Callable[[Any], Any]=json.loads) -> None:
87        """Return parsed JSON data.
88        .. versionadded:: 0.22
89        """
90        return loads(self.data)

May be it would be better if it return type was absent?

Yes, it is an error.
Return type should be Any.
