Support using PutObjectAsync return a HttpStatusCode and throw Exception when StatusCode not equal 200

[lengochiep99]

PutObjectAsync return a PutObjectResponse, but property HttpStatusCode and ResponseContent is a internal. I checked log, and HttpStatusCode is 400, but cann't access the attribute ResponseStatusCode

Yes, we need to change these properties to public

minio-dotnet/Minio/DataModel/Response/GenericResponse.cs

Line 29 in 7440578

internal string ResponseContent { get; }

minio-dotnet/Minio/DataModel/Response/GenericResponse.cs

Line 30 in 7440578

internal HttpStatusCode ResponseStatusCode { get; }
