Improve dataset card for MathVerse: Add task category, tags, and related survey link

This PR improves the dataset card for `MathVerse` by:
- Adding the `image-text-to-text` task category and `mathematical-reasoning`, `multimodal`, `geometry`, and `benchmark` tags to the metadata for better discoverability.
- Including a link to the related survey paper, "[A Survey of Deep Learning for Geometry Problem Solving](https://huggingface.co/papers/2507.11936)", which references this dataset as a key resource in visual mathematical reasoning. A link to the survey's continuously updated GitHub reading list ([https://github.com/majianz/gps-survey](https://github.com/majianz/gps-survey)) is also provided.
