Inherit from modpacks in launcher
Description
Basically what this function does is, that when creating a new modpack you can choose something like "base this modpack on ..."
I find it very annoying to add all LabyMod addons again and again when creating new modpacks.
So I'd like to just create a modpack and say that this should be based on the default modpack for example.
Would save a lot of time especially when creating modpacks with many fabric mods.
