kubectl: make error with resource list prettier

Browse Source 
Previously, running commands like `kubectl get` with no further
arguments would print a list of valid resource types with an error
messages formatted like so:

    <snip>
      * serviceaccounts (aka 'sa')
      * services (aka 'svc')
      * statefulsets (aka 'sts')
      * storageclasses (aka 'sc')error: Required resource not specified.
    Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).
    See 'kubectl get -h' for help and examples.

This commit adds extra spacing so it now looks pretty:

    <snip>
      * serviceaccounts (aka 'sa')
      * services (aka 'svc')
      * statefulsets (aka 'sts')
      * storageclasses (aka 'sc')

    error: Required resource not specified.
    Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).
    See 'kubectl get -h' for help and examples.
