documenting array[T] instead of array[object]

```go
type userArrayResponse struct {
Body struct {
Users []sql.User `json:"users"`
}
}
```

In the generated OpenAPI docs, `UserArrayResponseBody` schema shows an `array[object]` text which I would like it to say `array[User]`. Documented JSON is correct for User. I've looked for some time but was not able to get this, like trying to implement SchemeProvider etc.

Reproduce the generated OpenAPI documentation with the provided Go userArrayResponse example, then trace the schema-generation path around SchemeProvider. Check how the []sql.User field is named in the displayed schema while preserving its already-correct JSON representation. Done means the schema text shows array[User] instead of array[object].
