Handshake Headers's Typing should by "any" instead of "object" (v3.1.0)

[Julien-Marcou]

Description

When retrieving the cookie property from the socket's handshake headers, typescript's typing is giving the error Property 'cookie' does not exist on type 'object'.

To reproduce

Socket.IO server version: 3.1.0

Server

import { Server } from 'socket.io';

const io = new Server(3000, {});

io.on('connection', (socket) => {
  // Property 'cookie' does not exist on type 'object'
  console.log(socket.handshake.headers.cookie);

  // Ok
  console.log((socket.handshake.headers as any).cookie);
});

Expected behavior

We should be able to retrieve the cookie property without casting the headers to any.

A better typing could be Record<string, any>.

The same goes for the query attribute (socket.handshake.query) I think.
