chore: skip tests View fixtures from rector

[samsonasik]

Description

Resolve notice:

Run vendor/bin/rector process --dry-run --no-progress-bar

Warning: ] The following files were skipped as starting with short open tag.    
           Migrate to long open PHP tag first:                                  
                                                                                
           tests/system/View/Views/apples.php                                   
           tests/system/View/Views/broken.php                                   
           tests/system/View/Views/extend.php                                   
           tests/system/View/Views/extend_include.php                           
           tests/system/View/Views/extend_reuse_section.php                     
           tests/system/View/Views/extend_two.php         

they are fixture files, so no need to be scanned by rector.
