Datasets cannot be downloaded in the colab

Running the first and second cells of the "download datasets" section of the google colab linked in the readme results in
```
Downloading 1 datasets to ~/tensorflow_datasets.

FileNotFoundError: [Errno 2] No such file or directory: 'kuka/0.1.0/dataset_info.json'

The above exception was the direct cause of the following exception:

FileNotFoundError Traceback (most recent call last)
FileNotFoundError: Could not load dataset info from kuka/0.1.0/dataset_info.json

The above exception was the direct cause of the following exception:

FileNotFoundError Traceback (most recent call last)

382 exception = RuntimeError(f'{type(e).__name__}: {msg}')
--> 383 raise exception from e
384 # Otherwise, modify the exception in-place
385 elif len(e.args) <= 1:

FileNotFoundError: Failed to construct dataset "kuka", builder_kwargs "{'data_dir': '~/tensorflow_datasets'}": Could not load dataset info from kuka/0.1.0/dataset_info.json
```

(I selected only the kuka dataset but the exception is identical with the others).
