Update README.md

This is a dataset of various user reviews posted on the IMDb website along with their corresponding ratings. There are three files attached here, one each for the training, validation and test data. The training dataset contains 60,459 entries. Both the validation and the test data files each contain 12,956 reviews and their associated ratings. The master dataset used for splitting into these 3 files was close to perfectly balanced in nature, and since these datasets are 'stratified' on the target column, they also contain an equal number of items (nearly) for each target rating class.
