upgrade from 0.2.2 to latest version with already running containers

Hello!

I'm currently on version 0.2.2 and would like to upgrade to the latest version of colima. The README says that I have to use `colima delete` and then `colima start` because I'm upgrading from pre 0.3.4.
I couldn't find out in the docs if `colima delete` will also remove the data thats stored in my container volumes/colima VM.

I have a postgresql container I'm using for development and which I would like to keep using after the upgrade.

So how can I upgrade colima from 0.2.2 to 0.4.2 without loosing my container data/volumes? Will `colima delete` keep the data and just remove the VM without touching my container volumes?

Thanks!
