Revert "Update SafetyHubDisruptiveNotificationRevocation fieldtrial_testing_config"

This reverts commit 43bb21096287096e523fe97ef150ea0cc201d553.

Reason for revert: Mistake on my side. For the finch configuration we actually need the previous version. Again, this is anyway a no-op.

Bug: 406472515
