Aricle on Medium needs updating for Google UI changes

**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The article on Medium includes an outdated description of how to get config data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

If the article can be amended that would be great

Open the linked Medium article and locate the section describing the “Web Setup” button and its config modal. Update that section to use Project Overview > Project Settings > General > “Firebase SDK snippet” > “Config”, then verify the article reflects the current Google UI.
