Prater Genesis Bootstrapping

If you have not run a Prater Prysm node yet, you will need to download the pre-generated genesis state for prater and provide the beacon node flag --genesis-state=/path/to/prater/genesis.ssz.
The genesis.ssz state file can be found in the eth2-clients/eth2-networks repo.

Thank you all for the support!
