add "__set_state" to Handlers to allow laravel config cache

[Curicows]

I have a project that uses the Laravel framework. I'm using the TelegramBotHandler to handle logs.

"telegram" => [
    'driver'  => 'monolog',
    'handler' => FilterHandler::class,
    'tap' => [TelegramFormatter::class],
    'level' => "debug",
    'with' => [
        'handler' => new TelegramBotHandler(
            apiKey: env('TELEGRAM_API_KEY', ""),
            channel: env('TELEGRAM_CHANNEL', ""),
            level: Level::Debug,
            parseMode: "MarkdownV2"
        )
    ]
],

While it works perfect in the local environment, when I try to cache the Laravel config an error is thrown:

laravel@ubuntu:/path/to/project$ artisan optimize

Inspecting the generated file before the "LogicException" has been thrown resulted in this cache:

'telegram' => 
      array (
        'driver' => 'monolog',
        'handler' => 'Monolog\\Handler\\FilterHandler',
        'tap' => 
        array (
          0 => 'App\\Log\\TelegramFormatter',
        ),
        'level' => 'debug',
        'with' => 
        array (
          'handler' => 
          \Monolog\Handler\TelegramBotHandler::__set_state(array(
             'level' => 
            \Monolog\Level::Debug,
             'bubble' => true,
             'processors' => 
            array (
            ),

             'delayBetweenMessages' => false,
             'topic' => NULL,
          )),
        ),
      ),

The error occurs because when Laravel cache the config that directly instantiates an object it is transformed to call the static magic method "__set_state" of the class used. But an error is thrown because the Handler classes doesn't have this magic method.

I'm able to create a pull request to resolve that and if more information is needed I can provide it, thanks for the attention.
