Update showcase.json

I was going through the website and as I scrolled all the way down to the bottom , I observed  that out of 12 logos of the React Native users , three didn't show any updates on mouseovers . So just checked in with the source code and Updated it .

I think this was necessary because it doesn't seems nice to the viewer .

An alternative can be till the time there is someone writes blogs for these three users , You can replace them with the any three users like 
Vogue , Soundcloud , Discord etc

Hope this is useful for the community and devs.
