Fix deprecation from core 9.4

Problem/Motivation

PHPStan found a deprecation:

Line   modules/custom/menu_per_role/menu_per_role.module                    
 ------ --------------------------------------------------------------------- 
  101    Call to deprecated method getImplementations() of class              
         Drupal\Core\Extension\ModuleHandlerInterface:                        
         in drupal:9.4.0 and is removed from drupal:10.0.0. Instead you       
           should use ModuleHandlerInterface::invokeAllWith() for hook        
         invocations                                                          
           or you should use ModuleHandlerInterface::hasImplementations() to  
           determine if hooks implementations exist.                          
 ------ --------------------------------------------------------------------- 

I will also increase core requirement to 9.4
