Document `/api/download` endpoint

[allejo]

The new Download page is powered by the /api/download endpoint that should be documented for others to use. This endpoint accepts POST requests with a JSON body in the following format.

{
  "api": 2,
  "languages": []
}

A proposed addition is to add a format key that would allow for zip or javascript to download the compiled bundle in the respective format

I assume this is only building the "just include it via <script>" common JS monolith (like the old website)... if someone wanted ES modules we'd just point them to the existing CDNs or Git repos?
