Bug 36837: (follow-up) UNIMARC case

I checked the UNIMARC authResults counterpart file. And it only
contained a single case of generated elements like the previous patch.

To test:
1. On latest main
   $ ktd --shell
  k$ cd misc/translator/po
  k$ git fetch
  k$ git reset --hard origin/main
  k$ cd /kohadevbox/koha
  k$ gulp po:update --lang es-ES
  k$ cd misc/translator/po
  k$ git add -u ; git commit -mWIP --no-verify
2. Apply this patches
3. Run:
  k$ cd /kohadevbox/koha
  k$ gulp po:update --lang es-ES
  k$ cd misc/translator/po
  k$ git diff
=> SUCCESS: Notice CSS class names are not translated anymore
