Docs are not clear how to close PendingConnection

[3noch]

The docs state

websockets/src/Network/WebSockets/Server.hs

Line 203 in ff17c79

-- 'PendingConnection' should be closed using 'Stream.close' later.

But the linked close works on Streams not PendingConnections. To get a PendingConnection's Stream you must use pendingStream which is only exported by Network.WebSockets.Connection which has a scary warning at the top that you shouldn't use be importing it unless you know what you're doing.
