Describe the solution you'd like

When we have a release with the new AMI changes it the re-enable the following tests:

• Clusterctl Upgrade Spec [from latest v1beta1 release to v1beta2]
  • Failing as the test needs to use an older released version of CAPA and this relies in AMIs that are no longer available
• Cluster Upgrade Spec - HA control plane with workers [K8s-Upgrade] [ClusterClass]
  • We need to change the expected etcd of this test to3.5.15-0
• Self Hosted Spec [ClusterClass]

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]

Environment:

• Cluster-api-provider-aws version:
• Kubernetes version: (use kubectl version):
• OS (e.g. from /etc/os-release):
