In release package, image path does not match image path specified in definitions

In 192-02-21:

eng:
  id: 192-02-21
  terms:
  - type: expression
    normative_status: preferred
    designation: down time
  definition: |-
    time interval for which the item is in a down state

    image::/assets/images/parts/192/60050-192-F1en.png[Figure 1 - Times related to operation and maintenance]
  language_code: eng

Here the image file path is:

/assets/images/parts/192/60050-192-F1en.png

But it is actually this in the release package (the path differs, filename also differs).

images/parts/192/192-F1en.png

We need to make this consistent.
