language badges with shiki in code blocks

[enolive]

I wonder if there is any way I am missing to add a language badge to a codeblock (similar to my question some years ago, see #385 ) with shiki.

I'm pretty sure that by writing a transformer, this functionality could be attached to the existing codebase.

atm I have a working implementation in my own slidev theme. Ping me if I should provide a PR!
