Make it easier to update minecraft .jar / mod loaders

[NunoGomes-Coding]

Description

Make some sort of a button (as an example) where we're able to update minecraft's .jar or the fabric/forge mod loader to the latest stable or a desired version, similar to when we are a creating a new instance.

I'm aware it is possible to perform it using the file manager, but having a feature to simplify this process is always welcome.
