'./mach try auto' for ESR 115 repository causes decision task timeout due to bugbug timeout

[Archaeopteryx]

'./mach try auto' had been executed for the ESR 115 tree by a developer twice and it failed each time due to a bugbug timeout during the run of the decision task. The issue was reproducible with a Try push by me
