What steps did you take and what happened:
[A clear and concise description of what the bug is.]

I deployed an AWS Managed Machine Pool and tried to specify and AWS launch template with amiType: AL2023_x86_64_STANDARD on EKS 1.33.

apiVersion: infrastructure.cluster.x-k8s.io/v1beta2
kind: AWSManagedMachinePool
metadata:
  name:  eks-pool0
  namespace: capa
spec:
  eksNodegroupName: pool0
  scaling:
    minSize: 1
    maxSize: 2
  amiType: AL2023_x86_64_STANDARD
  awsLaunchTemplate:
    instanceType: m7i.4xlarge
    instanceMetadataOptions:
      httpPutResponseHopLimit: 2

I got the following error:

Failed to reconcile launch template:
failed to get ami SSM parameter:
"/aws/service/eks/optimized-ami/1.33/amazon-linux-2/recommended/image_id": ParameterNotFound:

What did you expect to happen:

No error

#5517 seems to be the solution

@afarbos Should we close this now that #5517 has been released?

Yes, I realize now it's a bit unrelated to this issue purely but it would be nice to be able to template the AWS launch template I am not sure how to configure the nodeadm config without CAPA information (api server address....)
