JsonbSerializer's javadoc example is most likely misguided

[This line of JsonbSerializer's javadoc's](https://github.com/eclipse-ee4j/jsonb-api/blob/b29bc1edff86b66f2b57476b394e5da19f47ac40/api/src/main/java/javax/json/bind/serializer/JsonbSerializer.java#L40) exemplifies its use by calling the method `SerializationContext.serialize(T object, JsonGenerator generator)` , that is "_intended to serialize inside JSON_ARRAYs_"¹, which is not the case.

The intended example is more likely

`ctx.serialize("boxInnerObject",boxInnerObject,generator);`

which uses the `serialize` version with a key parameter.

Open api/src/main/java/javax/json/bind/serializer/JsonbSerializer.java at the referenced javadoc example and compare it with the SerializationContext.serialize overloads linked in the issue. Update the example to use the overload with a key parameter, then verify that the javadoc matches the intended serialization context.
