    docs: update uci's wireless reconfiguration text
    
    "wifi detect" has been replaced by "wifi config". It no longer
    needs the file redirection to /etc/config/wireless.
    
    It also removes the half sentence about rebuilding the
    configuration when installing a new device. I think it is
    bad advice to nuke the entire existing configuration just
    to add a new wifi device.
