nodejs*: normalise names to better fit other packages

#### Pitfalls {#javascript-node2nix-pitfalls}

- If upstream package.json does not have a "version" attribute, `node2nix` will crash. You will need to add it like shown in [the package.json section](#javascript-upstream-package-json).

- `node2nix` has some [bugs](https://github.com/svanderburg/node2nix/issues/238) related to working with lock files from NPM distributed with `nodejs-16_x`.

- `node2nix` has some [bugs](https://github.com/svanderburg/node2nix/issues/238) related to working with lock files from NPM distributed with `nodejs_16`.

- `node2nix` does not like missing packages from NPM. If you see something like `Cannot resolve version: vue-loader-v16@undefined` then you might want to try another tool. The package might have been pulled off of NPM.
