Wrong DST Steam deck compatibility tool

Steam deck can not use external keyboards and trackpads, and all keyboard-mouse mappings are invalid. The Linux version is compatible with steam deck, allowing you to easily switch between the keyboard and the controller. New players currently have to manually change steam deck's default compatibility tool to“Steam Linux Runtime 3.0(sniper)” to have a good experience. It is a mistake to use a buggy and unmaintained“Proton 9.0-2” compatible tool for steam deck by default. I recommend changing steam deck's default compatibility tool to“Steam Linux Runtime 3.0(sniper)”, preferably focusing on maintaining the Linux version and forgoing steam deck proton to reduce developers' work.
