Clean caсhed files

[devintly]

This is an improvement, not a bug. It would be nice to add a clear cache parameter to the discord-portable.yml file. How to clear the cache: you need to delete the "Cache", "Code Cache", "GPUCache", "Session Storage" folders, which are located in the "Discord Portable\data" directory. Thank you!
