fix: installation on eks

There is an issue installing Rancher Turtles on EKS using the chart as the kubernetes version in EKS doesn't follow semver. For example, EKS will return a version like `v1.26.12-eks-5e0fdde` and this means that we then try and pull the `docker.io/rancher/kubectl:v1.26.12-eks-5e0fdde` image when performing the cleanup tasks. The function to strip the suffix from the kubernetes version has been updated to handle EKS, AKS and GKE. Signed-off-by: Richard Case <[email protected]>
