Proton installation could not be found due to config.vdf casing

[EvoSteven]

Protontricks wouldn't work for me initially and it seems like both valve and steam were lowercase in my config.vdf, which didn't work with what protontricks expected (vdf_data["InstallConfigStore"]["Software"]["Valve"]["Steam"]).

Changing those to be properly cased in the vdf file made it work for me. Not sure what caused this or how common it is but figured I should report it all the same.

The new Steam beta came with multiple breaking changes: many VDF fields are now lowercase and the structure of libraryfolders.vdf is now different. I've pushed changes to vdf_all_lowercase branch that should hopefully resolve all the new issues.

You can install and test the fixes by installing Protontricks using pipx. You can check the README and follow the instructions for the most part, but use the following pipx install command instead:

$ pipx install --force git+https://github.com/Matoking/protontricks.git@vdf_all_lowercase

Could you check whether this lets you run Protontricks properly again?

[EvoSteven]

Great! Tested it and the vdf_all_lowercase branch seems to work properly on my end.

[Matoking]

Good, I'll merge the fix into master. Thanks for the help!
