Support Markdown previews for embed codes

[castrojo]

Is your feature request related to a problem? Please describe.
The embed code is great so projects can flex their stats, however they don't render on statically generated sites like docusaurus or github readmes because they're iframes.

Describe the solution you'd like
Support a markdown thing with an image or something that can be embedded easily in a github readme. Also for things like a github readme, it might be nice to just have one "executive brief" dashboard that is a single widget but with the important things on it (see below).

Describe alternatives you've considered
Repobeats does this well and gives people the markdown snippet to generate the final result (link):
