Expand description

Based on Config. Auto-generated by #[pallet::config(with_default)]. Can be used in tandem with #[register_default_config] and #[derive_impl] to derive test config traits based on existing pallet config traits in a safe and developer-friendly way.

See here for more information and caveats about the auto-generated DefaultConfig trait and how it is generated.
