* Update yuzu.sh
- perform update check only if launching mainline release
-
* yuzu-EA qol improvements
- update shortcut + icon if using EA
- download EA metadata only once
- use .temp file to download EA, rename and chmod +x it after download
- do not start update if EA metadata is missing for some reason
- added YuzuEA_uninstall()
+ set yuzu.ver in Yuzu_install() so that yuzu.sh updater doesn't ask for update
* Update emuDeckYuzu.sh
- moved yuzu-ea.AppImage check outside tokenFile check (launcher would still find yuzu-ea)
