Add other pictures than icon in the documtation for better visualization

[flomickl]

For a better output visualization, I added a second png

## Output

<p align="center">
    <img src="output.png" width="500;"/>
</p>

which exists in the resource folder.

Currently, this picture doesn't show up in the documentation.

Do I miss something? It seems that only the name icon.png can be "rendered "
Do I miss something?

Since the documentation file is a simple Markdown file, it shouldn't be a problem to include another image
I just played around a bit and got it sometimes working with the same code as above and sometimes not, seems to be a bit flaky
@dominikriemer @tenthe do you have any experience here?

Hey,
you sample looks good to me. I have done this before (e.g. [1]).
The only difference I see is the "px" for the width. But I am not sure if this is the reason for the inconsistent behavior.

Did you register the icon in the declareModel method?

ah, good point. I have not done it and probably this will solve the problem.

@dominikriemer @tenthe
I implemented it as described here

streampipes/streampipes-extensions/streampipes-processors-geo-jvm/src/main/java/org/apache/streampipes/processors/geo/jvm/jts/processor/derivedgeometry/point/CreateDerivedPointProcessor.java

Line 69 in 6a00daf

.withAssets(Assets.DOCUMENTATION, Assets.ICON, "derivedPoint.png")

and in the document here
https://github.com/apache/streampipes/tree/1321-geo-create-derived-point-of-input-geometry-processor/streampipes-extensions/streampipes-processors-geo-jvm/src/main/resources/org.apache.streampipes.processors.geo.jvm.jts.processor.derivedgeometry.point

but still the same as above.
Do I miss anything?

Have you reinstalled the pipeline element?
This is necessary to update the assets.

[flomickl]

Yes. I also cleaned my browser cache and because I switched the branches, I also did a StreamPipes clean -v
In the normal markdown preview, I can see the image.
