Adding self-decidable minecraft versions

As I noticed, you can't manually add any Vanilla Minecraft Versions to the launcher, which is really annoying if you want to play on servers which are not on the latest version of a full release (like 1.18.1), so i would request to add a feature with which you can manually add versions to the list already included in the main menu, just like on the normal launcher.
