Bring Minecraft Dungeons support to the official Linux & SteamOS Launcher

The official Minecraft Launcher already provides native packages for Debian, Arch, and other Linux distributions. While Java Edition runs smoothly, spin-off games like Minecraft Dungeons cannot run on Linux or SteamOS through the official launcher due to Microsoft Gaming Services dependencies.

Since Minecraft Dungeons works on SteamOS via Steam, please consider adding Proton compatibility or native support for Dungeons directly into the official Linux Minecraft Launcher.

Players who purchased Minecraft Dungeons directly from the official store should be able to play on Steam Deck / Steam Machine and/or Linux without needing to buy the game again on Steam.
