Updated for Valet 4

[davemac]

Can you update this for Valet 4, as I cannot make a pull request. Here is the updated driver:

<?php

namespace Valet\Drivers\Custom;

use Valet\Drivers\ValetDriver;

     * @return bool

    public function serves(string $sitePath, string $siteName, string $uri): bool
    {

@davemac I have been having problems accessing the /wp-admin pages after including this new driver; a 404 nginx error to be exact. I just wanted to make sure that this doesn't have anything to do with the driver.

Same getting 404 with the above

I've fixed the wp-admin issue here, if anyone needs this:
