fix predis clear() when using redis 7.4

[vintagesucks]

Hi! We noticed that horizon:clear-metrics stopped working after upgrading Redis from 7.2.6 to 7.4.1.

To reproduce, run:

laravel new example-app -n
cd example-app
composer require "laravel/horizon:5.30" "predis/predis:2.3.0"
REDIS_CLIENT=predis php artisan horizon:clear-metrics

When using Redis 7.2.6:

   INFO  Metrics cleared successfully. 

When using Redis 7.4.0 or 7.4.1:

   Predis\Response\ServerException 

  ERR invalid cursor

  at vendor/predis/predis/src/Client.php:416
    412▕             return $response;
    413▕         }
    414▕ 
    415▕         if ($this->options->exceptions) {
  ➜ 416▕             throw new ServerException($response->getMessage());
    417▕         }
    418▕ 
    419▕         return $response;
    420▕     }

      +19 vendor frames 

  20  artisan:13
      Illuminate\Foundation\Application::handleCommand(Object(Symfony\Component\Console\Input\ArgvInput))

A similar issue was recently fixed in symfony/cache, and applying that fix to Horizon seems to fix the problem when testing locally against the three Redis versions mentioned.
