Subject: [PATCH] More error checking and casing

* Translate GH's 403 to 503
* If/when the dep gets updated, gracefully handle GH's 403 as much as possible at authenticated and non-authenticated requests.
* The *@octokit/auth-token* dep returns lower casings for `authentication` and `basic`... not sure if matching this makes a difference but today I've been getting 45 maximum on unauthenticated GH rate limiting with this. Post #1729

Applies to #1705 #37
