Replace assignTestFlightGroup boolean with testFlightGroup choice

Lets the dispatcher pick which TestFlight group an iOS build gets
assigned to (QA Team, Software Mansion, or none). Previously the
input was a boolean that always pointed at "QA Team". Nightly build
keeps current behavior by passing "QA Team" explicitly.
