[Feature request] Delete cache folder when game is removed and caches are checked to be cleared

Quick summary

Case was missed when cache folder removal was pushed through

Details

A case was missed when adding the cache folder being purged when caches are cleared from a game. When a game is removed and the option to clear caches and custom configs is checked, the folder remains with its structure. I'm assuming it just got missed, I would fix it myself but I haven't had the chance to dive in and figure out how the code works
