kbenv list remote does not show rate limit error, when github api rate limit is reached

[EHJ-52n]

When the GitHub API rate limit is reached, the command kbenv list remote returns a not enduser friendly error message:

~ kbenv list remote
An error was detected, exiting: json: cannot unmarshal object into Go value of type []versions.Page
~ curl --silent -L https://api.github.com/rate_limit | jq -Mr '.rate'
{
  "limit": 60,
  "remaining": 0,
  "reset": 1690816864,
  "used": 60,
  "resource": "core"
}
~

Please improve the error message including a translation of the reset timestamp, hence the user knows, when this command will return useful information again.
