Deprecate Old Version of Cronos zkEVM chain (#6052)

* Deprecate Old Version of Cronos zkEVM chain

@ligi, there's a new iteration of Cronos zkEVM testnet and the official chainId has changed from `282` to `240`. 

This PR is deprecating the older version of testnet. I will create another PR to add a new chainId.

* Update RPC in eip155-282.json

* Update the chain and shortName info
