    Saves results to a JSON file. Also saves system information such as current time, current commit
    hash if inside a repository, and Python system information.

    Args:
        path_or_file (`str`):
            Path or file to store the file. If only a folder is provided
            the results file will be saved in the format `"result-%Y_%m_%d-%H_%M_%S.json"`.

    Example:
        ```py
        >>> import evaluate
        >>> result = {"bleu": 0.7}
        >>> params = {"model": "gpt-2"}
