nixos/redmine: Fix PNG generation of Gant diagrams 



The Ruby gem `minimagick` is used to export Gant diagrams as PNG.
However, minimagick can't find a font and Redmine throws an error. The
setting `minimagick_font_path` allows configuring a path to a font file
in the Redmine configuration. Thus, add the option
`services.redmine.components.minimagick_font_path` allowing to do that.

Also, add an assertion to check if
`services.redmine.components.minimagick_font_path` is set when
imagemagick is enabled.
