Avoid failure when trying to delete a bucket that doesn't exist

### Describe the feature

Currently when launching: `aws s3 rb s3://$BUCKET_NAME --force`
I get an error if the bucket doesn't exist. I'd like to have more flexibility in this case because deleting a bucket or seeing that it doesn't exist lead to the same result (bucket absence).

### Use Case

Throwing an error is something that can prevent a program or a pipeline from being correctly executed. A warning message could be more appropriate imho.
