Update CI Docs (#942)

## Description
Updating the CI documentation to work with a 74+ RNW application.

### Why
Tried to use our CI documentation to add CI to a 74 application and it
did not work straight out the box. Updating our CI documentation to use
the right dependencies. Also added the whole file because it helped me
figure out how to get CI working :)

+ name: Windows CI
+ on: [pull_request]
 
- - name: Setup Node.js
- uses: actions/setup-node@v1
