[BUG] function j_loader does not properly raise when input file non-existing and not with expected extension name

[kirk0830]

Bug summary

def j_loader(filename: Union[str, Path]) -> dict[str, Any]:
    """Load yaml or json settings file.

    Parameters
    ----------
    filename : Union[str, Path]
        path to file

    Returns
    -------
    dict[str, Any]
        loaded dictionary

    Raises
    ------
    TypeError
        if the supplied file is of unsupported type
    """
    filepath = Path(filename)
    if filepath.suffix.endswith("json"):
        with filepath.open() as fp:
            return json.load(fp)
    elif filepath.suffix.endswith(("yml", "yaml")):
        with filepath.open() as fp:
            return yaml.safe_load(fp)
    else:
        raise TypeError("config file must be json, or yaml/yml")

If the file is not found, it will raise TypeError, but this is not the expected behavior: in this case, should raise FileNotFoundError instead.
