docs: Add description about img in artifact-visualization.md

Motivation

It is difficult to know that img can link to play demo.

Modifications

Therefore I add description of img.

Verification

I didn't even know this was a video, nice change!

I am thinking though that there are better, more conventional ways of indicating that it is a video:

1. Embed the video directly in the page
2. Use an image with a play button in the middle (or otherwise overlay such a play button)

@GeunSam2 suggests to me as follows...
I contemplated the idea of generating and incorporating a distinct image, but it seemed challenging to upload a new image to a public repository and guarantee its credibility. Consequently, I opted to add a caption at the bottom of the image!

This is still an improvement over what it was before, so I'm ok with this.

The docs/assets/ directory has many images already, so one could be added there.

Nice! LGTM, thanks for iterating on this!

Actually I have tried to use <iframe> tag to embed the video directly, it can't apply.
However I find out that <iframe> tag is not supported in Github Markdown. (Disallowed Raw HTML (extension) or Stack Overflow) If you know how to embed the video in Github markdown, please let me know.

Yea it's not allowed in GH Markdown (no interactive elements basically), but I would think it would work on the rendered docs site. Did it not work on the docs site?
