Improve DEB package extraction and repackaging logic

Enhanced the workflow to handle multiple data archive compression formats (xz, gz, zst) when extracting and repackaging DEB files. Added checks for the presence of the data archive and updated extraction and repackaging commands to match the detected format, improving robustness and compatibility.
