adding marathi-wiki dataset
Can you make it a draft PR until you've added the dataset please ? @ekdnam  Done Thanks for your contribution, @ekdnam. 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.
