Is there a way to install later versions of `supertokens-core`? Do we have to uninstall the first package? Or does the next version already provide away to take care of all that?

Ah, I see in the docs that you can run `supertokens uninstall`. My guess would be that to upgrade, we would do that and then install the new version.
