Update GeoDE dataset card: add task category, GitHub link, and correct paper title/BibTeX

This PR improves the dataset card for the GeoDE dataset by:
- Adding `task_categories: ['image-classification']` to the metadata, improving discoverability on the Hugging Face Hub.
- Updating the main title of the dataset card to `# GeoDE: a Geographically Diverse Evaluation Dataset for Object Recognition` for better clarity.
- Updating the displayed paper title within the content to `GeoDE: a Geographically Diverse Evaluation Dataset for Object Recognition` while retaining the existing arXiv link as per instructions.
- Adding a link to the GitHub repository: `https://github.com/princetonvisualai/geode_dataset`.
- Updating the BibTeX entry to the official NeurIPS version found in the GitHub README.
