Multiple installs in single run

[caunt]

Add ability to install multiple versions of the game in single execution:

portablemc start --dry mojang:1.12.2,mojang:1.13,mojang:26.1

I am not sure about allowing to run multiple versions in same time, but at least for dry installation, it could help me with simplifying CI/CD enviroments preparation.

Thank you for your work! 😊

Quite a nice idea honestly, don't know what others thinks about this?

EDIT: Is it not possible for you to run the command multiple times? Or is there some kind of race condition you are running into? It might be worth improving the concurrency rather than adding a new CLI feature?

It works fine when executing portablemc for each version directly, I just though it would be great to have such a feature within a single run 😇

There would definitely be room in the future for concurrency, failure-handling and other optimizations
