Asciidoctor-pdf with kroki extension generates error for nomnoml diagram type

@Mogztter (Guillaume Grossetie) suggested I open an issue here.

I’m using the extension found here: https://github.com/asciidoctor/asciidoctor-intellij-plugin/blob/master/src/main/resources/kroki-extension.rb with kroki server to generate a nomnoml diagram.

Details:

• Asciidoctor-pdf (1.5.3), with this docker: https://github.com/madduci/docker-asciidoctor-pdf#docker-asciidoctor-pdf
• Kroki docker (0.5.0) https://docs.kroki.io/kroki/setup/install/#_using_docker

Asciidoc error:

asciidoctor: WARNING: could not embed image: /tmp/image-20200611-1-16whoip; image file is an unrecognised format

Asciidoc producing the error:

@Mogztter Yes, that did it! While we are at it, we should also pass the float + width + height +link attributes as well.
