Write a dataset_description.json for the derivatives folder.

>>> from smriprep.data import load
>>> from pathlib import Path
>>> from tempfile import TemporaryDirectory
>>> tmpdir = TemporaryDirectory()
>>> bids_dir = load('tests')
>>> deriv_desc = Path(tmpdir.name) / 'dataset_description.json'

>>> write_derivative_description(bids_dir, deriv_desc.parent)
>>> deriv_desc.is_file()
True

>>> tmpdir.cleanup()
