That seems to generate svgs which as far as I know no site will show og embeds with svgs for some reason

There are already a lot of choices to convert SVGs to PNGs, what Vercel uses is https://github.com/yisibl/resvg-js. And Sharp is another good option.

I use svgs for my websites og images, haven't come across an issue with embeds on most platforms.
