.npmrc

# Feature Request

- Add `.npmrc` file to assert using `https://registry.npmjs.org` registry.

## Motivation Behind Feature

https://lists.apache.org/thread.html/raa963b0c2349e8d08d6c2f9d557b9055402d6410d35d4e9573b63cab%40%3Cdev.cordova.apache.org%3E

To summarize, for users who have alternate NPM configurations and use private and/or NPM mirrors, it can be easy to install packages from a source other than the official NPM registry without realizing it. It's in Cordova's interest to ensure that NPM runs with a configuration of using the official NPM registry.

We can correct this via adding an `.npmrc` file to each of our repos with the following config:

```
registry=https://registry.npmjs.org
```
