JsonPath for private properties

### Is there an existing issue for this?

### Is your feature request related to a problem? Please describe the problem.

I created class with private property setter (DDD style) and use it for JsonPath. I received error "The property at path 'Name' could not be updated."
```
public class Product
{
public string Name { get; private set; }
}

[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
[HttpPatch]
public void Patch([FromBody] JsonPatchDocument p)
{
var prod = new Product();
p.ApplyTo(prod);
}
}

```

### Describe the solution you'd like

I'd like to update property value when property setter is private. DDD approach and RichModel is very popular now, a lot of teams creates encapsulated model classes with private setters. Other JsonPath implementations allows to initialize properties with private setters.
PocoAdapter class can be fixed
