Simplify PHPCS action in workflow file

Refactored the PHP Coding Standards action block in Github workflow file (.github/workflows/phpcs.yml). Removed redundant steps, and migrated job definition to use the prepared PHP coding standards action. This change provides a cleaner and less error-prone setup, allowing more focus on PHP Coding Standards execution.
