Is it possible to add documentation to enums?

**Describe the issue**

When your endpoint returns a model containing an enum, there is no way (that I know of) to add a descriptive text to each possible enum value. The ` [OpenApiProperty]` attribute doesn't work on enums. Maybe this is not possible in C# for technical reasons, but there is support for it in the [swagger spec](https://swagger.io/docs/specification/data-models/enums/) afaik

```
[JsonConverter(typeof(JsonStringEnumConverter))]
public enum Status
{
[OpenApiProperty(Description = "This invoice is paid")] // <-- does not work.
Paid,
Unpaid,
}
```
