Add an option to disable auto hiding keyboard

[Egor Gorbachev]

Now Telegram driver automatically hides keyboard for interactive messages:

driver-telegram/src/TelegramDriver.php

Lines 164 to 173 in cba2774

 public function messagesHandled() 
 { 
     $callback = $this->payload->get('callback_query'); 
  
     if ($callback !== null) { 
         $callback['message']['chat']['id']; 
         $this->removeInlineKeyboard($callback['message']['chat']['id'], 
             $callback['message']['message_id']); 
     } 
 } 

This method is called here:

For my case it is required to prevent hiding keyboard, but I did not find a way to do this without extending TelegramDriver and overriding messagesHandled. My suggestion is to add an option to TelegramDriver config, for example 'hideKeyboard' => true (default) and hide a keyboard only if this parameter is set to true. Can make a PR.
