docs: Creates a config of special modules that alter the default loader behavior. - "extensions": manipulate the default module resolution (steal-conditional) - "toMap": list of module identifiers that won't be converted statically to numeric ids and need to be resolved during runtime (dynamic imports) - "identifiersToResolve": list of module identifiers that will be manipulated by the resolve hook exposed by extensions.
