[PATCH 1/1] Dockerfile: add imagemagick

[Heinrich Schuchardt]

In reStructured text documentation we sometimes find formatting problems.
So we should add 'make htmldocs' to our Gitlab Ci steps and let all
warning result in a build failure.

For building the htmldocs target without warnings we need the ImageMagick
package.
