Specifying the RPC URL for the burner

[carletex]

This might be too niche, but I'm in a situation where I need to specify the RPC for the burner connector.

Currently, it's using the [0] first default RPC from the chain: /~https://github.com/scaffold-eth/burner-connector/blob/main/packages/burner-connector/src/burnerConnector/burner.ts#L56

Make sense, since we need to handle case for multiple chains it should be object:

Plain wagmi:

const rpcUrls = { 11155420 : 'https://sepolia.optimism.io/' };

export const config = createConfig({
  chains: [mainnet, base],
  connectors: [burner({ rpcUrls })],
  transports: {
    [mainnet.id]: http(),
    [base.id]: http(),
  },
});

While using rainbowkit wallet:

import { rainbowkitBurnerWallet } from "burner-connector";
rainbowkitBurnerWallet.useSessionStorage = true;
rainbowkitBurnerWallet.rpcUrls = { 11155420 : 'https://sepolia.optimism.io/' };

Will tinker with this later 🙌
