One detail I just realised, that might be worth writing down in a comment or something: indexes are NOT stable between DuckDB versions, and while they were not also before this PR, after this there is no real way to do so after adding settings.

And a minor nit: config options listed this way are all ones from core-extensions (and some like vss might not be autoloadable).

These functions are meant for iterating, and all this does is return information (the name/description). I don't think this really needs to be documented.
