Confusing repo names

https://github.com/xxfoundation/elixxir-xxdk-Examples README.md should probably be updated to say that's now in https://github.com/xxfoundation/xxdk-examples/tree/master/other-examples.

Or maybe elixxir-xxdk-Examples should simply be archived and redirected to the new one... There are two xxDK Example repos now, which is confusing.
