Can you say who is behind vsmarketplacebadges.dev? A little wary of a supply chain attack with that.

@andyleejordan this seems to be the official github regarding the vsmarketplacebadges.dev site. It is the only site i could personally find that is still able to generate Marketplace badges, and i saw it used by different extensions already since the changes of Shields.io. I personally dont see an issue with the sinte since the links are specifically svg, but if you have a problem with that i will just completely remove the badges and the problem is fixed. We can of course go with BadGen as mentioned in the other PR, but i dont see a difference between the two and the reason that that Repo hasnt had any uptates is probably because there have not been any issues with the project
