Improve dataset card with task category, project page link, and paper link

This PR improves the dataset card by:

- Adding the `text-generation` task category to improve discoverability.
- Including a link to the project page for more context.
- Ensuring the paper link is present and correctly formatted.

These additions enhance the dataset card's clarity and usability for researchers.

 # MaLA Corpus: Massive Language Adaptation Corpus
 
 This version contains train and validation splits.

 ## Dataset Summary
 
 The **MaLA Corpus** (Massive Language Adaptation) is a comprehensive, multilingual dataset designed to support the continual pre-training of large language models. It covers **939 languages** and consists of over **74 billion tokens**, making it one of the largest datasets of its kind. With a focus on improving the representation of low-resource languages, the MaLA Corpus is a critical resource for advancing multilingual models, particularly those aimed at serving underrepresented languages.
