Access wallet from keystore in scripts | `vm.getActiveWallet()`

Describe the feature you would like

Let's say I want to use the vm.sign feature in foundry.

vm.sign(private_key, digest);

Right now, if I've imported my wallet and am using it as a keystore, I cannot use the private key directly to sign things in my script.

It would be great to enable this, even if it had to prompt us every time to re-sign. Perhaps something like a vm.getWallet API.

Full Sign.sol:

// SPDX-License-Identifier: MIT
pragma solidity 0.8.24;

import {Script, console2} from "forge-std/Script.sol";

contract Sign is Script {
  function run() public {
    bytes32 message = "hi";
    Wallet memory activeWallet = vm.getWallet();
    (uint8 v, bytes32 r, bytes32 s) = vm.sign(activeWallet.privateKey, message);
    console2.log(uint256(v));
    console2.logBytes32(r);
    console2.logBytes32(s);
  }
}

Then, from the command line:

forge script script/Sign.sol --sender xxxx --account yyyy
