feat(config): auto-generate default and minimal configs as TOML asset files

[DaniPopes]

Component

Forge

Describe the feature you would like

Currently config options are manually documented in either the config crate's README.md or the book.

As a follow-up to #6753, auto generate the default and minimal configs as TOML files alongside the schema in crates/config/assets for documentation and reference purposes.
