Generate image for mermaid cards and use as link preview

[jtemporal]

before each card had a thumbnail that showed the image for a given card. With mermaid each individual page has the same thumbnail which is the website image not the corresponding card.

Maybe we can automatically generate the image for preview with JS and SVG

Update here: some of the logic to implement SVGs was done, but right now it only generate the svg for the command itself and not the full card =)
