fix: handle missing .versand_s for service categories like … (#579)

There are categories which are not require shipping and there is no
shipping field

## ℹ️ Description
For example category 297/298 does not require shipping, because its a
service category.
The current code did not handle that case and was searching for a path
with .versand_s, but in this category, there is no such path.

## 📋 Changes Summary

If the shipping_type is set to NOT_APPLICABLE in the configuration, the
shipping assignment step is skipped instead of being forced.
