    Filters out key-value pairs from the given dictionary where the value is None.

        dict_obj (Dict): The dictionary to be filtered.

        Dict: The dictionary with key-value pairs removed where the value was None.

    This function creates a new dictionary containing only the key-value pairs from
    the original dictionary where the value is not None. It then clears the original
    dictionary and updates it with the filtered key-value pairs.
