ValidationEventDecorator (Smithy API 1.47.0)

```
public interface ValidationEventDecorator
```
Validation event decorators take validation events and transform them by adding more contextual information, usually adding a hint to let the user know what can it be done to solve the issue. This might add context specific information that is not relevant for all cases such as links to internal knowledge sites or explicit instructions relevant only to the context where Smithy is being used.
