bug: kflex init crashes

[MikeSpreitzer]

Describe the bug

With kflex release 0.9.3 installed via homebrew, kflex init --create-kind eventually fails with the following complaint.

Error: error installing chart: error downloading the OCI chart oci://ghcr.io/kubestellar/kubeflex/chart/kubeflex-operator:9 : ghcr.io/kubestellar/kubeflex/chart/kubeflex-operator:9: not found

Steps To Reproduce

1. When there is no kind cluster named kubeflex, issue the command kflex init --create-kind

Expected Behavior

Successful creation of a kubeflex hosting cluster.

Additional Context

Here is a log demonstrating the problem.

mspreitz@mjs13 ~ % mkdir testkf

mspreitz@mjs13 ~ % cd testkf

mspreitz@mjs13 testkf % kind get clusters
No kind clusters found.

mspreitz@mjs13 testkf % which kflex

Usage:
  kflex init [cluster-name] [flags]

Flags:
  -c, --create-kind                  Create and configure a kind cluster for installing Kubeflex
  -d, --domain string                domain for FQDN (default "localtest.me")
  -p, --external-port int            external port used by ingress (default 9443)
  -h, --help                         help for init
  -n, --host-container-name string   Name of the hosting cluster container (kind or k3d only) (default "kubeflex-control-plane")

Global Flags:
  -s, --chatty-status       chatty status indicator (default true)
  -k, --kubeconfig string   path to the kubeconfig file for the KubeFlex hosting cluster. If not specified, and $KUBECONFIG is set, it uses the value in $KUBECONFIG, otherwise it falls back to ${HOME}/.kube/config (default "/Users/mspreitz/.kube/config")
  -v, --verbosity int       log level

[MikeSpreitzer]

This seems to have been broken by #451 .

So there is also CI bug: there is no test of kflex init --create-kind.
