In Tor Browser prefs, "dom.network.enabled" should have been "dom.netinfo.enabled"

Seems to have been a typo from legacy/trac#5642 (closed). Lucky for us, this pref is disabled by default in Firefox desktop and also the API is disabled by privacy.resistFingerprinting thanks to https://bugzilla.mozilla.org/show_bug.cgi?id=1372072. We could set "dom.netinfo.enabled" to false just to be safe, or just remove the "dom.network.enabled" line altogether.
