Laravel db:seed with Rollback option

Introduction
In the context of package development, particularly those involving database seeders, I propose the introduction of the --rollback option for the db:seed command. This feature complements the existing migrate:rollback command and offers a solution for efficient database seeding management.

The Problem
Currently, many projects rely on packages that utilize seeders to alter the database. However, when complications arise, such as errors, changes in requirements, or the need to remove packages, there is a lack of streamlined mechanisms to revert these seeding changes. While the migrate:rollback command helps with migrations, the absence of a corresponding option for seeders presents challenges in complex projects where multiple custom packages are involved.

The Solution
By introducing the --rollback option for the db:seed command, package developers and maintainers can now address these issues.

Use Case
Just run db:seed with the --rollback option and down() function will be invoked!

php artisan db:seed --class="Vendor\\Package\\Database\\Seeders\\UsersSeeder" --rollback 
#or
php artisan db:seed --rollback

namespace Vendor\Package\Database\Seeders

/** If your seeder does not extend the package's Seeder:
 * Sonole\LaravelDbSeedRollback\Illuminate\Database\Seeder
 * then a new temporary file will be created at database/seeders, and it will be deleted after down() execution. 
*/
use Illuminate\Database\Seeder;

class UsersSeeder extends Seeder
{
    /**
     * Seed the application's database.
     */
    public function run(): void
    {
         //\App\Models\User::factory(10)->create();

        // \App\Models\User::factory()->create([
        //     'name' => 'Test User',
        //     'email' => 'test@example.com',
        // ]);
    }

    /**
     * Reverse the effects of the database seeding operation.
     */
    public function down(): void
    {
        \App\Models\User::where('email', 'foo@bar.com')->delete();
    }
}
