Remove checks from WordPress iOS that now run on Danger

[mokagio]

The Dangerfile and dangermattic version I referred to for these changes was from b2a5d65112d6580c29c8b7f5ab33b00c35a0759d, https://github.com/wordpress-mobile/WordPress-iOS/tree/b2a5d65112d6580c29c8b7f5ab33b00c35a0759d

Notice I didn't remove the rules to run the ios-macos.ts checks because I noticed those checks include one for the Core Data model, which I couldn't find replicated either in dangermattic or in the local WordPress iOS setup.

Thanks! I was refraining for now to remove these checks already as we still need to have Danger run on label, milestone and other PR changes. I don't mind if we do it now but we need to be clear with what we'll be missing (hopefully, not for long 🙂 ).

Those are implemented here: Automattic/dangermattic#9
It's the last remaining pending PR. As soon as it's merged, I'll add calls to it together with other improvements.
