k9s doesn't honor KUBECONFIG environment variable when replacing value for plugin

[rvarunrathod]

k9s does not utilize the KUBECONFIG environment variable, when flag value of --kubeconfig is empty.

I am using plugin that will copy log command to clipboard.
The plugin

plugins:
 logs-kubectl-cmd:
   shortCut: Ctrl-L
   confirm: false
   description: Copy log cmd to clipboard
   scopes:
     - pods
   background: true
   command: bash
   args:
     - -c
     - "echo kubectl logs -f $COL-NAME -n $NAMESPACE --context $CONTEXT --kubeconfig $KUBECONFIG | pbcopy"

when I added logger here I found that value of *kcfg is empty

var cfg string
kcfg := c.Flags().KubeConfig
if kcfg != nil && *kcfg != "" {
  cfg = *kcfg
  log.Info().Msg(fmt.Sprintf("Here is the KUBECONFIG, %v, %v", kcfg, cfg))
}

logs

12:12AM INF Here is the KUBECONFIG, 0x14000c6f200,
