Replace the deprecated Google Api feed RSS to JSON service

The current demo uses the Google Api feed service which has been deprecated and no longer works. Therefore, after the initial yarn install && yarn start there are no news displayed on the Home page.

This might be quite confusing for newcomers as the demo shows these news.

A quick working fix might be to use rss2json.com like this:

...
const url = 'https://api.rss2json.com/v1/api.json?rss_url=https%3A%2F%2Freactjsnews.com%2Ffeed.xml';
...

and in the data handling section:

...
if (data.status === 'ok') {
  items = data.items;
}
...

Voala! The news are now showing properly.

@westrem I have made the changes also, but it requires a bit more than the above as the requested data doesn’t have exactly the same structure as before. publishedDate => pubDate, contentSnippet => content. The content field would need some truncation also to make it into a snippet, or just omit it completely as it isn’t really necessary. Did you want to make a PR on this? or shall I give it a go?
