Subject: [PATCH] Update GrandSlam authentication user agent

The akd/1.0 CFNetwork/978.0.7 Darwin/18.7.0 string dates from macOS 10.14.
Apple's GSA edge now allows only two requests per connection with it, and
sign in sends three, so the third always fails with an HTML 503 that surfaces
as NSCocoaErrorDomain 3840. A current AuthKit string raises that to four.

Port of rileytestut/AltSign#47 by @BreezeDelegate onto the notarized branch,
which AltStore's classic branches pin.
