Update README.md

This is a fix for the scrollOverflow functionality not working. I spent hours debugging this, and I realized this CSS file was missing.

[alvarotrigo]

The CSS file is include by default, see how the component includes it here:
https://github.com/alvarotrigo/react-fullpage/blob/master/components/ReactFullpage/index.js#L5

You can also see it on the dist file:
https://github.com/alvarotrigo/react-fullpage/blob/master/dist/react-fullpage.js#L5099

@cmswalker I think we need to get rid of it on the example file if we want to be consistent?
https://github.com/alvarotrigo/react-fullpage/blob/master/example/dist/index.html#L13

We'll probably need to change the webpack config for that?

[cmswalker]

Yes lets scrap it in example

I tried that, but the CSS did not take effect. Ah well. Thanks for the quick response. It's probably an issue on my end.

[alvarotrigo]

@shahzore-qureshi did you check if it was building the bundle file properly? Maybe it skipped the CSS inclusion due to lack of npm packages to include it?

Done!
I modified the package.json and the webpack.config.js files in order to solve it and add the CSS on the example build.
If there's anything you want to change let me know!
