Support diagrams.net (draw.io)

[JkbLskw]

In the kroki documentation, the diagram type "diagrams.net" (draw.io) is specified as experimental.
Unfortunately I couldn't find an issue regarding adding this diagram type to the asciidoctor-kroki extension.

Are there any plans for this?

Sure, we can add it.
Feel free to submit a pull request to add diagramsnet support.

We should also mention in the README that diagrams.net is not available on https://kroki.io.

Since kroki.io support is missing, I couldn't write a test for converting diagramsnet diagram to an image.

I only tested it locally with my own kroki server. Should I post the test result to this issue?

I misunderstood the tests. No real connection to kroki.io is created at all.
I added the test to convert a diagrams.net diagram to an image.
