Add --watch option to nutgram:run command

[Lukasss93]

This PR adds a --watch option to the nutgram:run command, which allows you to run the bot in watch mode.
This means that the bot will automatically restart whenever you make changes to the code,
making it easier to develop and test your bot.

Usage

To use the --watch option, simply run the following command:

php artisan nutgram:run --watch

Requirements

In your project, you should have the JavaScript package chokidar installed. You can install it via npm

npm install chokidar

or Yarn

yarn add chokidar

Configuration

You can configure the watch command in your config/nutgram.php file.

// ...

// Watch options used by the "nutgram:run --watch" command
'watch' => [

    // The paths to watch for changes
    'paths' => [
        app_path('Telegram'),
    ],

    // The extensions to watch for changes
    'extensions' => [
        'php',
    ],
],

@Lukasss93 @sergix44 This is my dream command 😃

Currently only php files are supported. Would it be better to make it configurable which extensions you want to support?
Example: json format translation files used by the bot, images, etc...

Maybe we could also move this to a config?
Something like:
$types = ['.php'];
That way it defaults to .php, but users can add other extensions if needed — like .json for bot translations, images, etc.
