Improve dataset card: Add task categories, links, tags, and data download instructions

This PR significantly enhances the dataset card by adding:
- `task_categories: ['text-generation']` to accurately reflect the domain.
- Relevant `tags` such as `diffusion-models`, `reinforcement-learning`, `math-reasoning`, `code-generation`, and `reasoning` for better discoverability.
- The `language: en` tag, as the content is in English.
- A descriptive title and an introductory overview of the dataset.
- Links to the associated paper ([https://huggingface.co/papers/2509.06949](https://huggingface.co/papers/2509.06949)), the GitHub repository ([https://github.com/Gen-Verse/dLLM-RL](https://github.com/Gen-Verse/dLLM-RL)), and the Hugging Face project page ([https://huggingface.co/collections/Gen-Verse/trado-series-68beb6cd6a26c27cde9fe3af](https://huggingface.co/collections/Gen-Verse/trado-series-68beb6cd6a26c27cde9fe3af)).
- A "Sample Usage" section with explicit `bash` commands for downloading datasets, taken directly from the GitHub README.
- The BibTeX citation for the associated research paper.

These additions provide essential information for users, making the dataset more accessible and easier to understand.

+# Revolutionizing Reinforcement Learning Framework for Diffusion Large Language Models Datasets
+
+This repository contains datasets used in the paper [Revolutionizing Reinforcement Learning Framework for Diffusion Large Language Models](https://huggingface.co/papers/2509.06949). These datasets are crucial for building, training, and deploying Diffusion Large Language Models (DLMs) within the TraceRL framework, particularly for improving reasoning performance on complex math and coding tasks.

+## Sample Usage (Data Download)
+
+You can navigate to the `./data` directory within the associated GitHub repository to download datasets for evaluation and training. In that directory, you will also find detailed instructions on how to modify your own dataset.
+
+For example, to download the `MATH500` and `MATH_train` datasets:
+
+```bash
+cd data
+python download_data.py --dataset MATH500
+python download_data.py --dataset MATH_train
+cd ..
+```
