    Create a partial function for validating a VAE (Variational Autoencoder) model.

    This function uses the training recipe defined in `train_vae()` to set up
    the model, data, trainer, logging, and optimization configurations for
    validation. It returns a Partial object that can be used by the NeMo run CLI
    to execute the validation procedure on the provided model and data.

    Returns:
        run.Partial: A partial object configured with llm.validate target
        and all necessary arguments extracted from the VAE training recipe.
