remove duplicate document in dataset

[srayuws]

Language Modeling part is duplicated at the start and between Entailment and Machine Translation

Currently, we have Wikitext2, WikiText103, and PennTreebank datasets in both experimental and normal folder. Not sure why you think they are duplicate.

In the documentation page https://pytorch.org/text/datasets.html here, there are two identical sections of Language Modeling :

https://pytorch.org/text/datasets.html#language-modeling, and
https://pytorch.org/text/datasets.html#id1

I think these two sections are duplicate? Or we need some more description about their difference?

Got it. I would rather remove the second one. Thanks.

Updated. Also added some empty newlines to make each section is separated by two lines as in other parts.
