Update version to 1.3.8 and improve XML version extraction logic.

Bump the program version number to 1.3.8. Refine the _xml_version function to handle case-insensitive checks for <extension> tags and ensure correct version extraction with enhanced depth evaluation for XML files. Simplify folder depth calculation and improve robustness of the logic.
