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.

Iniziate dal callback PushOptions.OnPushStatusError e dal percorso dell’errore di remote unpack descritto nell’issue. Riproducete il rifiuto della scansione dei segreti di Azure DevOps e tracciate il punto in cui il messaggio remoto dettagliato viene perso. Il lavoro è completato quando i chiamanti possono ricevere i dettagli dell’errore di remote unpack, incluso il messaggio VS403654, invece della sola eccezione generica.
