Feature request: add plugin badges

[binarynoise]

@Huderon created some great badges on Discord.
Could you please add it somewhere so we can use it in our READMEs, like https://docs.betterdiscord.app/branding/ which appears to be https://github.com/BetterDiscord/docs/tree/main/docs/public/branding ?

I think I'd be more apt to add it to the actual website rather than just the docs. But I'm open to other thoughts here.

For me as plugin dev it wouldn't make much of a difference.
I only asked here because I found this repo and it contained the other logos.
