[QGIS-Developer] Processing Help within Modeler wrong URL

[matteo]

Hi devs,

thanks to Alex work we have know solid anchors and url for Processing
algorithm help.

BUT, it seems that when the help button is clicked within the Processing
Modeler, the URL is not build correctly:

Wrong from modeler:

vs correct from Processing toolbox:

Cheers
