Anonymous users have a low (currently 60) rate limit of API calls.
Authorized users have a much higher (currently 5000) limit. Print the
available, used and remainling rate limit when the GitHub API returns a
403 messages like:
Error: 403 Client Error: rate limit exceeded
In case of anonymous access to the API, and hitting the limit, the
message in the logs will also include the following:
Rate limit (limit/used/remaining): 60/60/0
