feature: add deploy npm script to package.json

[sinedied]

Description

As part of schematics, it would be nice to also add a "deploy": "ng run <name>:deploy" npm script to follow usual nodejs project conventions. This is also a good thing to have when you don't have a global ng cli install, as you can directly use the local install this way, not needing to change anything on your env to deploy.
