archiving this repo

[dzmitry-lahoda]

Would be more clear https://docs.github.com/en/repositories/archiving-a-github-repository/archiving-repositories so that repo is not used anymore.

I see parity and other chains migrated to zombienet, and we too ComposableFi/composable#3204 (we proved that zombienet runs well on Nixos and under Mac M1 too).

We found no case when this repo did something which zombienet could not.

Archieval will confuse people less and direct more traffic to zombienet.

I would like that this repo get moved back to my github user now that it wont officially be maintained by paritytech.
