* Edited Dockerfile of Docker(Nginx) deployment doc

Edited `Dockerfile` section of https://cli.vuejs.org/guide/deployment.html#docker-nginx

As shown in [Vue v2 cookbook](https://vuejs.org/v2/cookbook/dockerize-vuejs-app.html) copying `package*.json` initially and running `npm install` in a separate step allows caching and reduces time elapsed during Docker build. Also the difference between the two docs will be reduced and be less confusing to those who end up with both of them.
