Steam proton saves files in your steam proton compatdata folder (where windows files are stored), you should look in there.
the way I open it is you go to "browse local files" or smth in the steam game, and you go back up the folder chain to "steamapps".
The compatdata folder should be in there, and you'll need to find the folder for silksong (by the app id on steam) which should be "1030300".
in there there should be "drive_c" or smth like that, that's the fake windows C drive. You can then go c:/users/steamuser/appdata/unity3d/team cherry or whatever and the save files should be there
~~Silksong is a Linux native game. No Proton is involved. OP is looking for the ~/.config/unity3d folder.~~
Edit: Nevermind, I just saw that OP is running it through Proton.
