fix(jsonschema): drop removed getBuiltinTypes path in SchemaPropertyMetadataFactory

The 4.4 readable-link refinement used a getType-gated dual path; main (5.0)
removed ApiProperty::getBuiltinTypes and property-info's getType, so on the
bumped Symfony floor the legacy branch fatally called an undefined method
during cache warmup (breaking every PHPUnit job). Keep only the native-type
branch, matching main's modern type handling.
