🔥 Remove specific PHP version preparation step in service file

The commit removes the previous `ExecStartPre` command that creates a dedicated directory for PHP8 in the service configuration. This change shows an effort to generalize the PHP configuration process, reducing the dependence on specific PHP versions. It will help minimize potential issues related to PHP version differentiation and simplify the PHP build process.
