Add OSCAR dataset card
CONTRIBUTOR
@lhoestq Thanks for the suggestions! I agree with all of them. Should I accept them one by one or can I accept them all at once? When I try to load the whole diff GitHub is complaining and it does no render them well (probably my browser?) 😅

I just merged the tables as suggested 😄 . However I noticed something weird, the train sizes are identical for both the original and deduplicated files ... This is not normal, in general the original files are almost twice as big as the deduplicated ones 🤔

Good catch @pjox ! I just checked and this is because the scripts doesn't handle having several blank lines in a row.
Blank lines introduced by deduplication are currently not ignored so we end up with the same number of examples in the dataset as the original version (but with empty examples...)
I fixed that in this [commit](https://github.com/huggingface/datasets/commit/837a152e4724adc5308e2c4481908c00a8d93383). I'm re-running the metadata generation for deduplicated configs.

great, I just wanted to report that I got error message "NonMatchingSplitsSizesError" when I tried to load one of the oscar dataset.

Ok I see you're having this issue because I haven't updated the sizes yet ! I'm opening a PR

I just checked and indeed there's an issue with the `deduplicated` configurations since the commit I mentioned above.
I'm fixing this by using the new sizes I got yesterday :)

I added more information and completed the dataset card for OSCAR which was started by @lhoestq in his previous [PR](https://github.com/huggingface/datasets/pull/1824).
