The following examples are equivalent:

path = tfds.core.tfds_path('path', 'to', 'data.txt')

Note: Even if `/` is used, those examples are compatible with Windows, as
pathlib will automatically normalize the paths.

*relative_path: Relative path, eventually to concatenate.
Returns:
path: The root TFDS path.
