[CI-SKIP] Fix the NMS Imports detecting our own files

the way I handled this on my fork was using the metadata in the
git "stats" output of patches, however we don't include stats in
the patch files for paper so the code didn't work.

Changed the code to detect our own file editions inside of NMS
to a method that works without stats.

So we no longer need to manually add files to this list
