ecs: Bottlerocket support for AsgCapacityProvider

[JZechy]

Describe the bug

I have this C# code that is defining Auto-Scaling group for ECS cluster with Amazon Image:

_cluster.AddAsgCapacityProvider(new AsgCapacityProvider(this, "asg-provider", new AsgCapacityProviderProps
        {
            AutoScalingGroup = new AutoScalingGroup(this, "auto-scaling", new AutoScalingGroupProps
            {
                AutoScalingGroupName = _clusterName,
                Vpc = _vpc,
                InstanceType = InstanceType.Of(InstanceClass.T3, InstanceSize.NANO),
                MinCapacity = 0,
                MaxCapacity = 5,
                MachineImage = EcsOptimizedImage.AmazonLinux2023(),
                InstanceMonitoring = Monitoring.DETAILED,
                SecurityGroup = ConstructSecurityGroup(),
                Role = CreateInstanceRole()
            }),
            CapacityProviderName = _clusterName,
            EnableManagedTerminationProtection = false,
            EnableManagedDraining = false,
            EnableManagedScaling = false
        }), new AddAutoScalingGroupCapacityOptions());

Security Group defines all requested connections. Role is defining everything that the ECS instance needs to work. Once the instance is created by ASG, is automtically registered with the ECS cluster and it's working. It is there, task is deployed, I can connect to the instance.

However if I change the MachineImage to new BottleRocketImage() as described in cdk docs, the registration of new EC2 instace stops working.

Expected Behavior

Bottlerocket instances should automatically register to the ECS cluster.

Current Behavior

Bottlerocket instance is created by ASG, but is not registered with the ECS cluster.

Reproduction Steps

Create a new ECS cluster with ASG as described above and select Bottlerocket as Machine Image.

According to this, BottleRocket image is only available with addCapacity() rather than addAsgCapacityProvider().

Before we clarify it in the doc I think you can reference this sample from the AWS Community Builder @neilkuan.

Making this a p2 feature request and we welcome your PRs if you successfully provision it.
