Aricle on Medium needs updating for Google UI changes

[seanburlington]

Describe the bug
The article on Medium includes an outdated description of how to get config data

To Reproduce
Steps to reproduce the behaviour:

1. Go to '...'
   https://medium.com/firebase-developers/how-to-setup-firebase-authentication-with-react-in-5-minutes-maybe-10-bb8bb53e8834#2be4

It says :

On the top of the Authentication page, click on the “Web Setup” button.

It will show up a modal just like this:

This is no longer how the Google UI works

Instead you need to go to

Project Overview > Project Settings > General > “Firebase SDK snippet” > Press “Config” radio button
