Directory links point to npm binaries

[mhosio]

The "view on npm" autogenerated link of a webcomponent deployed to Vaadin directory points to the binary version of the component in npm. I would expect it to point to something more human-readable.

Steps to reproduce:

1. Add a webcomponent to vaadin directory
2. Give the npm registry for your component (at this point the links are autogenerated)
3. Go to your add-on and click view on npm
   --> You will end up seeing "garbage" on the screen. See https://registry.npmjs.org/@vaadin-component-factory%2Fvcf-chat

Expected: I would rather see the link pointing to the npmjs.com main page of the component such as https://www.npmjs.com/package/@vaadin-component-factory/vcf-progress-spinner
