Use GNU_FORMAT in tarfile to avoid '././@PaxHeader' in archives

To address the issue where tarballs created by the archive_files function include unwanted '././@PaxHeader' directories, the tarfile creation mode has been switched to use the GNU_FORMAT. This change ensures that the tar archives generated do not contain these empty directories, resulting in cleaner and more compliant tar files.
