fix(amazonq): remove requestId param aws#6524

## Problem
1) we already have logic to show the user the request ID of the last
failed API call
2) we also already have logic to show them the failure reason
3) when a job is stopped, we don't expect anything to be present in the
`reason` field

## Solution
Remove param
