Fix argument count issue in `fs.mv` call within `TUDataset` download method

[ihkao]

Cause Analysis

The fs.mv function was incorrectly called with an extra recursive argument that is not supported by the LocalFileSystem.mv() method in the underlying file system handling library. Please see:

Traceback (most recent call last):

    fs1.mv(path1, path2, recursive)
TypeError: LocalFileSystem.mv() takes 3 positional arguments but 4 were given

Changes Made

Removed the unsupported recursive argument from the fs.mv call in the io.fs.py file.

Testing

Tested the download and processing of the ENZYMES dataset using the modified TUDataset class. The dataset downloads and processes without throwing the TypeError.
