* fix: Error on missing prettier config

When a prettier config file is specified but can't be found a default prettier config is silently used as a fallback.
This change causes an error to be raised when the specified prettier config doesn't exist.

Closes #908

* fix: Serialize falsey defaults and examples

Closes #890
