SWPROT-8953: docs: Adjust from unify to zpc

Use plantuml system (LSB) path if not overloaded

Use default zpc main docs file, until relocated elsewhere,
currently it is aligned to unify conventions.

It is preparing the day the desired version plantuml
land in most distros (see related links)

The alternative would be to port the sources
to widely available version.
