Documentation: Add GitHub CLI Tutorial

This is SUCH an important issue as it helps our community grow and allow the hurdles to contribute to lower. Here's the basic idea:

Create a comprehensive tutorial to help beginners navigate and contribute to the Legesher project using the CLI.

Using the toolbox document as reference (also seen on the documentation site) create a step by step walk through tutorial of the CLI tool for GitHub.

Begin with installation instructions with pictures and take them along the journey to fork a Legesher repository to their account & local machine all using the CLI.
