Describe the feature

Amazon ECS now supports built-in blue/green deployments.
https://aws.amazon.com/about-aws/whats-new/2025/07/amazon-ecs-built-in-blue-green-deployments/

Support was recently added to the aws-ecs module.

It would be great to have support added to the aws-ecs-patterns module also, so constructs such as ApplicationLoadBalancedFargateService can benefit from the feature.

Use Case

To allow uses of aws-ecs-patterns, such as ApplicationLoadBalancedFargateService, to make use of blue/green deployments.

Proposed Solution

Add properties for built-in blue/green deployments.
