Create a new Guide for how to enable autostart of Sunshine on KDE Plasma and Wayland without enabling autologin

[midwesternrodent]

Description

Add a new guide for how to enable autostart for Sunshine on KDE Plasma and Wayland without enabling autologin. This guide utilizes the existing guide by Eric Dong as the base, and then expands on it to enable the autostart functionality.

After following the guide, sunshine will start on boot, and moonlight will connect to the login screen.

There are a few caveats to this guide that I will update as I find workarounds:

1. It does not work with multi monitor setups
2. You cannot change the screen properties with a sunshine application prep command via kscreen-doctor as plasma has not initiated the screens when on the login screen. Attempting to do so will cause moonlight to fail to connect to the sunshine host. You can still modify the screens manually or via kscreen-doctor after you have logged into wayland.

However, if you agree I think it's ready for prime time for advanced users. I am looking to help out with documentation on a couple of projects in the near future so if you have any feedback for me on how I've handled this pull request, please let me know! Thank you for building an amazing FOSS solution!

I discovered that audio with pipewire is not working with this setup. I had only ever tested it over lunch at work so I didn't notice until last night!

I have a workaround but it will require a rework of this guide. I will re-open this PR once I've made those edits.
