Description

This PR adds missing icon and launch screen to FabricExample app.
After copying the icons from paper example i noticed there are icons for iPad and the example itself supports iPad platform. Thus I decided to add the iPad support to fabric example as well.

Changes

• added iOS icons and launch screen
• added iPad support

Great change! Just leaving one suggestion here.
In Reanimated, Example app and FabricExample app have different app icons. This allows the developer to visually distinguish app with old and new arch. Can we do something similar there? I would go for having an outline version of logo in FabricExample app, something like in our docs (maybe with gradient kept?) - you can find the logo here.

For reference, I'm also leaving links for reanimated logos:

I've also thought of that @tboba, but I don't think we have such graphic ready. Unless @alduzy can rustle one up in half an hour, otherwise I'm for merging this PR as is.

I've replaced the icon on fabric as @tboba suggested 😉

A load of new kilobytes for our repository (that hurts me), but fine :D 🟢
