chore: update appliance-mode values and docs

Update Appliance-Mode Values

Summary

I was tasked with evaluating an edge use-case and was directed to use the appliance-mode values. The values as written would not deploy on a 4CPU 16GB node. The changes in this MR successfully deployed and executed in my test environments. My goal was to keep CPU requests near 100% and limits near 200% and Memory requests near 50% and limits near 100%.
