is the way one runs e2e tests affected? should we add something in the readme about deploying a relayer fleet with a specific private key in env?

[ClementWalter]

latest run on staging:

• all errors are for ercXX test, error in argent multisig api
• failures are related to updated tests not matching the current deployed kakarot, mutlsig REVERTED raising instead of returning status, state not updated. I'll just investigate the messaging to make sure, otherwise all green to me

end-to-end tests could be pulling the state from SN Sepolia when starting Katana so that we run everything like on a sepolia deployment?
