Add support for pnpm install

[ia3andy]

Now that we have support for NodeJS and NPM install, adding pnpm should be a piece of cake:

quarkus.quinoa.package-manager-install=true
quarkus.quinoa.package-manager-install.node-version=16.17.0
quarkus.quinoa.package-manager-install.pnpm-version=7.12.0

Default download root: https://registry.npmjs.org/pnpm/-/

If implementing this, you might also want to implement #174
