ClientError class missing code and status properties in stackTrace

[marius-ciocoiu]

The ClientError class in the Vertex AI SDK doesn't include code and status properties in its type definition, despite these properties being present in the actual error object thrown by the API.

Current Behavior

The ClientError class is defined as:

declare class ClientError extends Error {
    readonly stackTrace?: Error;
    constructor(message: string, stackTrace?: Error);
}

However, when catching errors from the API, the actual error object includes a stackTrace property with code and status:

{
  "name": "ClientError",
  "stackTrace": {
    "code": 400,
    "status": "INVALID_ARGUMENT"
  }
}
