add wikipedia biography dataset
Does anyone know why am I getting this "Some checks were not successful" message? For the _code_quality_ one, I have successfully run the flake8 command. Ok, I need to update the README.md, but don't know if that will fix the errors Hi @ACR0S , thanks for adding the dataset!

It looks like `black` is throwing the code quality error: you need to run `make style` with the latest version of `black` (`black --version` should return 20.8b1)

We also added a requirement to specify encodings when using the python `open` function (line 163 in the current version of your script)

Finally, you will need to add the tags and field descriptions to the README as described here https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md#tag-the-dataset-and-write-the-dataset-card

Let us know if you have any further questions! Also, please leave the full template of the readme  with the `[More Information Needed]` paragraphs: you don't have to fill them out now but it will make it easier for us to go back to later :)  Thank you for your help, @yjernite! I have updated everything (finally run the _make style_, added the tags, the ecoding to the _open_ function and put back the empty fields in the README). Hope it works now! :) LGTM! merging since the CI is fixed on master
My first PR containing the Wikipedia biographies dataset. I have followed all the steps in the [guide](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md). It passes all the tests.
