[Documentation] Move the contents of documentation into docs

## Description of Documentation Need
There is a /documentation and a /docs folder - having both is confusing and not necessary
## Target Audience
Everyone

## Proposed Location
Move the naming convention into the docs folder (or conversely move all of the docs files and the runbook folder to /documentation) so there is only 1 documentation folder for all of it

## Content Outline / Draft
N/A - just cleanup folder structure

## Compliance Context (if applicable)
N/A
