[New chain]: Hemi Mainnet

[rokso]

Fixes #771

Singleton factory is deployed as part of predeploy and hence I am using values from OP chain artifact file.

Hmm, I'm actually not sure what the transaction and gas fields should be in this case... One issue I have with the current PR is that the signed transaction is not signed for the correct chain ID.

Sorry for the back-and-forth. We discussed internally and proposed the following for networks with pre-installed Safe Singleton Factory contracts:

Verified deployment code using the RPC from #771 with:

curl -s -X POST $RPC -H 'content-type: application/json' --data '{"jsonrpc":"2.0","id":0,"method":"eth_getCode","params":["0x914d7Fec6aaC8cd542e72Bca78B30650d45643d7","latest"]}' | jq -r .result

And that it is in fact a pre-installed contract (as the signer account has a 0 nonce):

curl -s -X POST $RPC -H 'content-type: application/json' --data '{"jsonrpc":"2.0","id":0,"method":"eth_getTransactionCount","params":["0xE1CB04A0fA36DdD16a06ea828007E35e1a3cBC37","latest"]}' | jq -r .result

Thanks @rokso!
