Make the RPC usage mandatory if needed.

[Ethnical]

In the task https://github.com/ethereum-optimism/superchain-ops/blob/main/tasks/eth/ink-001-permissionless-proofs/VALIDATION.md#0xde744491bcf6[…]teregistryproxy

We should make sure, that if the RPC usage is needed into the Validation file that there is an EXPLICIT way to get access and all the command needed to do it as mandatory and not OPTIONAL.

Feedback from a signer:

"If you have access to ink rpc url" is going to confuse people. It needs to be obvious what to do. It should be either "get an ink rpc url, this is how you get one and do this check" or it should be deleted

Thanks for raising this. Given that this task is more like a guideline and not something that can be actioned and completed permanently, I'm going to close this. I think you should raise this is you're reviewing PRs that aren't following this guideline. Let me know if you'd like to reopen, or I've misunderstood this.
