AWS::ImageBuilder::Image delete AMI when the stack is deleted

### Name of the resource

AWS::ImageBuilder::Image

### Resource name

_No response_

### Description

I am using AWS::ImageBuilder::Image through CDK [CfnImage](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_imagebuilder.CfnImage.html), so the please let me know if it's a CDK question.

Currently, AMI are created with AWS::ImageBuilder::Image in the stack. But when the stack is deleted, the AMI is still there. Is this expected ?

I would expect it to be deleted along side with the stack as any other resource type. Or is it possible to have a Rention flag option ?

### Other Details

_No response_

Start with the AWS::ImageBuilder::Image documentation and the linked CDK CfnImage reference. Confirm how AMI lifecycle is defined when the CloudFormation stack is deleted, including whether a retention option is specified. Done means the expected deletion or retention behavior is documented and the request has a clearly scoped implementation path.
