Feature request: Provide an API endpoint to query available diagram types

[jougs]

I checked both the (opened and closed) issues and pull requests here, as well as the documentation for kroki but could not find anything related to my request. Feel free to close (and maybe point me in the right direction) if this feature already exists and I was just too stupid to find it 😉

TL;DR: I'm currently writing a little frontend for kroki and would like to offer a dropdown menu for selecting the diagram type. Rather than providing the list manually (and possibly extending and fixing it whenever kroki gets updated) It would be incredibly helpful if kroki would provide an endpoint, which would give me a mapping of endpoints to names like this:

{
    "/blockdiag": "BlockDiag",
    "/c4plantuml": "C4 with PlantUML",
    ...
    "/wireviz": "WireViz"
}

This list could be dynamic based on the companions available and ease frontend development for everyone.

I found that Niolesk provides such a list together with its examples, but this also seems to assembled by hand.
