Kube version override

[brandtkeller]

Description

Adding a flag to the zarf prepare find-images command such that helm charts that implement a minimum kubeVersion field in the Chart.yaml can specify an override target Kubernetes version. That will allow zarf prepare find-images to specify a --kube-version that emulates the same activity that helm uses for helm template.

example/cert-manager is a temporary addition to allow testing with (success) and without (failure) the use of the new --kube-version flag

Overall looks good - one other change could be to line 160 of src/pkg/packager/prepare.go to change:

message.Errorf(err, "Problem rendering the helm template for %s", chart.URL)

to something like:

message.Errorf(err, "Problem rendering the helm template for %s: %s", chart.URL, err.Error())

That way people see the error in the warning message.
