karpenter version is not compatible with K8s version 1.31

[starlightromero]

Description

Observed Behavior:

Karpenter Helm chart version 1.0.4 is deployed.

In the controller logs:

{"level":"ERROR","time":"2024-09-30T17:55:44.159Z","logger":"controller","caller":"amifamily/ami.go:91","message":"failed validating kubernetes version","commit":"0f8788c","controller":"nodeclass.status","controllerGroup":"karpenter.k8s.aws","controllerKind":"EC2NodeClass","EC2NodeClass":{"name":"bottlerocket-node"},"namespace":"","name":"bottlerocket-node","reconcileID":"REDACTED","error":"karpenter version is not compatible with K8s version 1.31"}

Expected Behavior:

The latest version of the Helm chart would support the latest Kubernetes version. Furthermore, there would be no error logs about version compatibility issues.

1.0.4 is not officially tested with Kubernetes 1.31 and only officially supports up to 1.30. We're in the process of updating our CI infrastructure to test with 1.31, once that is complete the release will support 1.31.
