Update docs to fix reducer page

[jeparlefrancais]

There is still this on the Reducer page

local reducer = function(action, state)
    return {
        myPhoneNumber = phoneNumberReducer(state.myPhoneNumber, action),
        myFriends = friendsReducer(state.myFriends, action),
    }
end

Where the action and state parameters are inverted. It's already fixed in the docs it's just not published online yet.
