Sets `base_model: lerobot/fastwam_base` in the model card metadata, so this model shows up in its parent's model tree on the Hub. The parent comes from the `pretrained_path` recorded in this checkpoint's `train_config.json` (`lerobot/fastwam_base`). Also sets `license: apache-2.0`, the parent's license, since the card had none.
