[DOCS]: Fix / update generation for the docs for Octokit.rb

[nickfloyd]

Describe the need

Currently, as one of our contributors has pointed out, the docs located at: https://octokit.github.io/octokit.rb/ are about 5 years out of date.

We need to renew our docs by:

• Creating a way that the docs can be regenerated (we used yard in the past) each time a merge to master occurs
• The need to be hosted in a public location
• The approach should respect separation of concerns so that it can be properly tested, validated, and used as part of the dev cycle if needed.
