[aws-eks] EksOptimizedImage returns wrong image SSM path /aws/service/eks/optimized-ami/1.14/recommended/image_id

[IronforgeV]

EksOptimizedImage returns the wrong image ssm path without amazon-linux-2

`aws ssm get-parameter --name /aws/service/eks/optimized-ami/1.14/recommended/image_id --query "Parameter.[Name,Value]" --output text

An error occurred (ParameterNotFound) when calling the GetParameter operation:
`

aws ssm get-parameter --name /aws/service/eks/optimized-ami/1.14/amazon-linux-2/recommended/image_id --query "Parameter.[Name,Value]" --output text /aws/service/eks/optimized-ami/1.14/amazon-linux-2/recommended/image_id ami-0d373fa5015bc43be

Reproduction Steps

Create autoscaling group using EksOptimizedImage
asg = autoscaling.AutoScalingGroup( self, "KubeFleet", instance_type=InstanceType("t3.large"), machine_image=eks.EksOptimizedImage(), associate_public_ip_address=False, update_type=autoscaling.UpdateType.REPLACING_UPDATE, desired_capacity=3, vpc=vpc, vpc_subnets={'subnet_type': SubnetType.PRIVATE} )

This is 🐛 Bug Report

[eladb]

The issue here is that we don't honor the default for nodeType, so until this is fixed you can use:

new EksOptimizedAmi({ nodeType: NodeType.STANDARD });

Fix is on it's way through #7672
