ru_reviews dataset adding
Hi @lhoestq  

I have added the readme as well 

Please do have a look at it when suitable  Chatted with @darshan-gandhi on Slack about parsing examples into a separate text and sentiment field Thanks for your contribution, @darshan-gandhi. Are you still interested in adding this dataset?

We are removing the dataset scripts from this GitHub repo and moving them to the Hugging Face Hub: https://huggingface.co/datasets

We would suggest you create this dataset there. Please, feel free to tell us if you need some help.
