Capture error details of "remote unpack failed"

Reproduction steps

• create Azure DevOps repo with security rules enabled
• create commit which violates server rules. For example appsettings.json

{
    "Parameters": {
        "note": "this will trigger secret warning in the Azdo push, which is what I'm testing for",
        "secret": "opensesame"
    }
}

I configure the repo.Network.Push this way

var po = new PushOptions()
{
    CredentialsProvider = (_, _, _) => AzdoCreddentials,
                
    OnPushStatusError = (reason) =>
    {
        mainLogger.Log(LogLevel.Error, "Push failed with {}", reason.Message);
    },
};

Expected behavior

Make PushOptions.OnPushStatusError or another callback to receive details of remote unpack failure similar to git CLI

Specifically error: remote unpack failed: error VS403654: The push was rejected because it contains one or more secrets. in the log below.

Comience con el callback PushOptions.OnPushStatusError y la ruta del fallo de remote unpack descrita en el issue. Reproduzca el rechazo del escaneo de secretos de Azure DevOps y rastree dónde se pierde el mensaje remoto detallado. Se considera completado cuando los llamadores pueden recibir los detalles del fallo de remote unpack, incluido el mensaje VS403654, en lugar de solo la excepción genérica.
