Launcher doesn't work with the instance method

basically, if you create a copy of balatro.exe and rename it, it acts as a fresh copy of the game, with its own save directory that has the same name as the exe file and erverything. When selecting your game directory, you can't choose which specific exe file it should look for, or which save data folder, meaning it can only look at your main instance.

The reason I use this method is because it makes it easier to switch between different versions of steamodded and running different mods.

Start at the launcher flow for selecting the game directory, then trace how it locates the executable and save-data folder. Confirm how renamed Balatro.exe instances are represented, and consider the issue complete when a user can select the intended executable and corresponding save directory instead of only the main instance.
