Mark all games as playable in Linux

Thanks to the massive amount of advancements in Proton, almost every single game is playable in Linux, even if not natively. Most of my gaming happens in Linux. However, I am still forced to list all of that as played in Windows. Yes, we do use sites like ProtonDB to check first if something will work well in Linux. I just have no way to share here that that is how I played it. I would love to be able to check more games here as done in Linux.
