Quick Start Guide: Building Yocto for Raspberry Pi 4

This guide sets up Yocto for a Raspberry Pi 4, using the scarthgap branch and enabling SSH access via Dropbear. It also includes steps for setting up Wi-Fi credentials, using the ghcr.io/crops/poky:ubuntu-22.04 Docker image, and configuring Shared State Cache for faster builds.
