[9.x] Allow set command description via AsCommand attribute

[dinhquochan]

Currently, if we use the AsCommand attribute, it will not be set to $description of the class, because Laravel command overrides this property.

This PR will allow us to use AsCommand to set the description of the command class.

ExampleCommand.php using AsCommand:

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Symfony\Component\Console\Attribute\AsCommand;

#[AsCommand('example', 'This is an example command')]
class ExampleCommand extends Command
{
    // 
}
