Dataset "definite_pronoun_resolution" cannot be loaded
**Short description**

The link for the dataset "definite_pronoun_resolution" does not work now.(http://www.hlt.utdallas.edu/~vince/data/emnlp12/train.c.txt). Seems like we also need to contact the dataset authors.

**Environment information**
* Operating System: Ubuntu 18.04.5 LTS (in Colab)
* Python version: 3.7
* `tfds-nightly` version: tfds-nightly-4.4.0.dev202109290107
* `tensorflow` version: 2.6.0

* Does the issue still exists with the last `tfds-nightly` package (`pip install --upgrade tfds-nightly`) ?

Yes

**Reproduction instructions**

```python
import tensorflow_datasets as tfds
tfds.load("definite_pronoun_resolution")
```

**Expected behavior**
