Dashboard documentation could use a note about timeout: 0 for Hardhat projects

[gnidan]

As surfaced in trufflesuite/truffle#5967, Hardhat defaults to a 40 second timeout for provider requests sent to localhost networks. This might not be enough time for users to carefully review their transaction.

Our Truffle Dashboard docs should include the suggestion to specify timeout: 0 inside their network configuration, since this will disable the timeout and give users as much time as they need.

Example hardhat.config.ts with timeout disabled

import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";

const config: HardhatUserConfig = {
  networks: {
    "truffle-dashboard": {
      url: "http://localhost:24012/rpc",
      timeout: 0
    },

    // ... other networks
  },

  // ... rest of hardhat config ...
};

export default config;

Another option to explore is that maybe we can send a bunch of newlines at least once every <40s to "trick" Hardhat into not timing out. It's possible that HH will still timeout, but perhaps not likely. (@davidmurdoch thinks it's just an idle timeout)
