Fails to deserialise when type is a record

```csharp
public record Config(
string test);
```

```csharp
var options = new JsonSerializerOptions()
.SetMissingMemberHandling(MissingMemberHandling.Error);
JsonSerializer.Deserialize("{\"test\":\"test\"}", options);
```

```
Unhandled exception. System.MissingMethodException: Cannot dynamically create an instance of type 'TestProject.Config'. Reason: No parameterless constructor defined.
```

No source file or test is named. Start by reproducing the JsonSerializer.Deserialize example with SetMissingMemberHandling(MissingMemberHandling.Error), then trace the deserialization entry point for record construction; done means the record deserializes from the shown JSON without MissingMethodException while retaining the requested missing-member behavior.
