aws_ecs: BaseService.register_load_balancer_targets() got an unexpected keyword argument 'container_name'

[kcong7714]

Describe the bug

I have a my_service instantiated from aws_ecs.FargateService(). A container my-container is added.

I want to register load balancer target as per documentation:
https://docs.aws.amazon.com/cdk/api/v2/python/aws_cdk.aws_ecs/FargateService.html#aws_cdk.aws_ecs.FargateService.register_load_balancer_targets

It throws error:
TypeError: BaseService.register_load_balancer_targets() got an unexpected keyword argument 'container_name'

Expected Behavior

Able to add container my-container of my_service to a new target group, added to the specified listener.

Current Behavior

It throws error:
TypeError: BaseService.register_load_balancer_targets() got an unexpected keyword argument 'container_name'

Reproduction Steps

        my_service = aws_ecs.FargateService(
            self, 'MyService',
            cluster=cluster,
            service_name='my-service',
            task_definition=ecs.FargateTaskDefinition(
                self, 'MyTaskDefinition',
            ),
        )

        my_service.task_definition.add_container(
            'MyContainer',
            container_name='my-container',
            image=ecs.ContainerImage.from_registry(name=CONTAINER_IMAGE_URI),
            port_mappings=[ecs.PortMapping(container_port=int(CONTAINER_PORT))],
        )
        
        my_service.register_load_balancer_targets(
            container_name='my-container',
            container_port=int(CONTAINER_PORT),
            new_target_group_id='MyTargetGroup',
            listener=ecs.ListenerConfig.application_listener(
                listener=listener,
                protocol=elbv2.ApplicationProtocol.HTTP,
                priority=1,
                conditions=[elbv2.ListenerCondition.host_headers([MY_DOMAIN_NAME])],
            )
        )
