BUG REPORT: EventBridge Scheduler does not allow FIFO Dead Letter Queues

I believe I found a defect in the new EventBridge Scheduler product:

1. FIFO SQS queues require FIFO deal letter queues (https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-dead-letter-queues.html )

2. When attempting to create a Schedule that targets a FIFO SQS queue, if you specify a FIFO dead letter queue, then the request fails because the regex used to validate the DLQ ARN does not allow for a ".fifo" suffix.
