Add non-steam game to steam when installing console arcs

About the console arcs install I asked about in #higurashi
I had a look into it and Non-Steam Game shortcuts are saved in a shortcuts.vdf file, this file is saved in Steam\userdata[STEAMID]\config\
I've tried opening in N++ but it has a lot of characters that don't display correctly,I have found these pages about editing it

I've used GLoSC to set up some games with my Steam Controller, and it adds the shortcut automatically and then restarts Steam which reloads the shortcuts.vdf file

I don't know how it could be implemented in the installer, but I imagine that something like this would work to have a Console Arcs shortcut automatically added to Steam after install and I hope that something here might help with it

该 issue 是关于在安装控制台 arc 后，将非 Steam 游戏快捷方式添加到 Steam。研究涉及理解 shortcuts.vdf 文件格式，该文件位于 Steam userdata 配置目录中。查看链接的 Python VDF 库和 Steam Shortcut Manager，了解如何读写此文件。安装程序可能需要检测已安装的游戏可执行文件，创建快捷方式条目，并可能重启 Steam。首先检查现有的安装程序代码，查看安装后步骤的处理位置。
