[miladkhodaverdi23]

This pull request introduces a new feature to the Update class in the Telegram Bot SDK, allowing for the extraction of commands from callback_query updates. The enhancement adds a getText method that processes and retrieves command strings from callback queries, improving command handling efficiency.

Changes
New getText Method: Added to the Update class to handle command extraction from callback_query updates.

Usage:
Example Keyboard
You can use inline keyboards to send callback queries:

Keyboard::make()
    ->inline()
    ->row([
        Keyboard::inlineButton([
            'text' => 'Access',
            'callback_data'  => 'access',
        ])
    ]);

Example Command Usage
Command class utilizing the new feature:

class CallbackAccessAccountCommand extends Command implements CommandInterface
{
    protected string $name = 'callback:::access';
    protected string $description = 'Access account';

    /**
     * @throws Exception
     */
    public function handle()
    {
        // Command implementation
    }
}

Please review the changes and provide any feedback or suggestions.
