feat(docx): Adding a QuickStart guide for Atlantis

[scotttjob]

Motivations

1. I've gotten Atlantis up and running from scratch a few times now, but the info for how to is in my head.
2. It's useful to have a page we can point LLMs to, that gives them the knowledge on how to use our component library.

Changes

1. Added a new guide for Atlantis Quick Start

Added

1. A new guide for Quick Start/Getting Up and running

Testing

1. On web, you should be able to create a new Vite React/Typescript app, and follow the web instructions to get up and running with Atlantis.
2. On mobile, you should be able to create a new Expo app, and follow the mobile instructions to get up and running with Atlantis. Expo is currently behind our RN version, so the --legacy-peer-deps command is required. If they catch up, we should be able to remove that guidance.

Changes can be
tested via Pre-release
