OpenApiRequestBodyAttribute Example parameter is ignored

The example object used for the Example parameter in OpenApiRequestBodyAttribute appears ignored.

I've added the OpenApiRequestBodyAttribute to an HTTP trigger function as below:
`[OpenApiRequestBody("application/json", typeof(Trip), Required = true, Example = typeof(TripExample))]`

Implementation of the TripExample class is below
```
public class TripExample : OpenApiExample
{
public override IOpenApiExample Build(NamingStrategy namingStrategy = null)
{

Examples.Add(OpenApiExampleResolver.Resolve("manifest", "Example trip advice json document.",
new Trip
{

EventHeader = new EventHeader
{
...
Code I've skipped for brevity
...
},
namingStrategy));

return this;
}
}
```

If I specify the example using the OpenApiExampleAttribute the swagger doc renders correctly. I cannot do this outside of a PoC though because the request objects are implemented in their own class library and I don't want to include a dependency on this library.
