Update restore-sql-pool-from-deleted-workspace.md

I updated the below as the desired date time selection should not be an approximate timeframe it needs to be explicit, or it will fail. 


# Define the approximate point in time the workspace was dropped as DroppedDateTime "yyyy-MM-ddThh:mm:ssZ" (ex. 2022-01-01T16:15:00Z)
$PointInTime="<DroppedDateTime>" 
$DroppedDateTime = Get-Date -Date $PointInTime
