🐞 Describe the bug

ref: https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent
current: https://github.com/aio-libs/aiohttp/blob/707736b/aiohttp/http_websocket.py#L31-L42

The close code 1014, 1015 is missing, and one of my use case (websocket proxy) involves 1014,
which results in an unexpected error "Invalid close code: 1014".

I think we need to update the list.
