Document Alongside mode SteamShell runs in either of two modes now, and the wiki described only one. Adds a page for the pair, and threads it through Install, Home, Settings, the tray page and the sidebar. The Install page's product table had two answers where there are now three: Alongside is the one to start with on a machine that is also a PC, rather than XFE, which is for Xbox FSE rather than for caution.
Add screenshots to the Quick Menu, and add Settings Editor and Desktop & Tray pages Weaves the 2.0.2 screenshots into the existing Quick Menu page rather than replacing it, and adds two pages nothing covered: a visual tour of the desktop Settings editor, and the tray menu. The Quick Menu's Pages section named four pages -- Main, Tasks, Settings and Game Detection -- and the screenshots show seven: Audio, Display & HDR, RTSS & Performance, Current App and System are all top-level now, and Game Detection is a row under System rather than a page. Corrected against what the build actually draws.
