Tor-hosted NoScript updates

From this release on, NoScript versions for Tor Browser are hosted on Tor's infrastructure, allowing us to deliver more timely and reliable updates. Distinguished by a version number ending with ".1984", they are otherwise equivalent to their AMO (stable) or pre-release counterparts: e.g. 13.5.2.1984 (Tor) = 13.5.2 (AMO).
