add GitHub storage adapters

[rccsousa]

Why:

• the deployment was attempting to store/fetch data locally which isn't a possibility in the current setup, implicating the need to setup cloud storage;

How:

• to address the issue a new payload-compatible storage adpater has been created to enable this build as a git-based CMS using Octokit to manage files;
