Move away from yarn #576
Description
I'm still on yarn v1. I tried to upgrade to yarn v3 in #26 but the present and future of the package doesn't look really good. Looks like I should move to either npm or pnpm.
npm seems to have support for a version command which I need: https://docs.npmjs.com/cli/v11/commands/npm-version
I also made good experiences wit pnpm.
