Wrong link for "Showfoto PDF version"

[Hans Schmidts (WEB)]

The link for "Showfoto PDF version" on 
https://www.digikam.org/documentation/ is wrong: It points to HTML 
version 
(https://docs.kde.org/trunk5/en/extragear-graphics/showfoto/index.html) 
instead of to PDF 
(https://docs.kde.org/trunk5/en/extragear-graphics/showfoto/showfoto.pdf 
- you can use this link to get "showfoto.pdf", so it's obviously 
generated correctly, simply wrong web site content).
