chore(deps): update dependency @types/node to v16 (#5170)

* Update Node types to 16

* Update Express core types

Fixes a number of conflicts it has with Node 16.

* Fix websocket router types

It seems req was `any` before so now we have to handle the types.  Also
it seems the socket is of type `stream.Duplex`, not `net.Socket`.

The ws types had to be updated to support the new type.

Unfortunately Code still uses the old type so cast for now.

In the web socket router just use a cast for the extra properties we
add.  We could add the types to the Express namespace but I am not sure
we really want these commonly accessible so keep with the casts for now.
Likely we should use Express's `locals` or something instead.

* Add missing return

Not sure why it only just now started complaining though.
