The sky attribute of MapLibre Style Spec may be invalid

[gisxuh]

In MapLibre Style Spec, there is a sky attribute that appears to be valid, but it is invalid in custom style.json. But in this website（ https://wifidb.net/demo/sky/terrain.html#6/47.265/11.404/0/60 ）There is a demo that uses a version of maplibre-gl-dev. js called v4.0.0 pre. 6, which is indeed effective. I compared this demo with the same version of code on the official website and made many modifications to achieve the sky effect. My native language is not English, and I hope community experts can understand what I am saying. Thank you for your efforts!

Sky is still experimental and wasn't really released in any official version.
I thought the docs stated that, but apparently they don't.
I'll take care of it.
