[fix] ensure that test.pyright installs pyright

nodejs.ensure only sets up NVM if there isn't a system-wide
installation of Node that matches our NODE_MINIMUM_VERSION.

The ubuntu image in the CI comes with an up to date node version,
so pyright from .nvm_packages is never installed.

This commit fixes this by introducing a package.json file.
