Improve dataset card: Add metadata, update Hugging Face and paper badges

This PR improves the dataset card for AetherCode by:
- Adding `license: cc-by-4.0` to the YAML metadata.
- Adding `task_categories: text-generation` to the YAML metadata.
- Adding `language: en` and relevant `tags` (`competitive-programming`, `code-generation`, `llm-evaluation`, `benchmark`, `reasoning`) to the metadata for better discoverability.
- Correcting the Hugging Face dataset badge link to point to the dataset's specific page (`https://huggingface.co/datasets/m-a-p/AetherCode`).
- Replacing the inconsistent "Leaderboard" badge with a "Paper" badge that links to the Hugging Face paper page (`https://huggingface.co/papers/2508.16402`), while retaining the existing arXiv link.
