Update the start time for the azure ci runs to be at 2 twice a day

[LoopedBard3]

Update the start time for the azure ci runs to be at 2 twice a day rather than 9 to ensure we don't have machines restart during testing. The goal of this is to fix machines become disconnected/unavailable as the daily update for them runs.
