With the Socks5 proxy enabled, the Coroutine HTTP client uses IPv6 addresses as domain names for DNS resolution

Please answer these questions before submitting your issue. Thanks!

1. What did you do? If possible, provide a simple script for reproducing the error.

   
   use Swoole\Coroutine\Http\Client;
   use function Swoole\Coroutine\run;

run(function () { $client = new Client('2600:1417:7800:8ad::180c', 443, true); $client->setHeaders([ 'Host' => 'www.qq.com' ]);

$client->set([
    'ssl_host_name' => 'www.qq.com',
    'socks5_host' => '127.0.0.1',
    'socks5_port' => 1067
]);

$client->get('/');
echo $client->errMsg;
echo $client->body;
$client->close();

});

2. What did you expect to see?
``` bash
DNS Lookup resolve failed.

3. What did you see instead? Proper handling of IPv6 addresses.

4. What version of Swoole are you using (show your php --ri swoole)?

   
   php --ri swoole

Changing socks5_host to [::] will fix，But set to [::] does not support IPv4 URLs.
