This PR improves the dataset card by:
- Adding `audio-text-to-text` to the `task_categories` metadata to better reflect the multimodal and generative nature of the dataset.
- Adding a prominent link to the Hugging Face paper page: https://huggingface.co/papers/2407.21054.
- Adding a direct link to the associated GitHub repository: https://github.com/leduckhai/Sentiment-Reasoning.
- Updating the "Dataset and Pre-trained Models" section to clarify that this repository is the dataset itself.
