This PR updates the FlowBench dataset card with the following improvements:
* **Adds `task_categories: ['other']`** to the YAML metadata for better discoverability. This categorizes the dataset within scientific machine learning and fluid dynamics.
* **Introduces links to the associated research paper** where a model using this dataset was presented: [Predicting Time-Dependent Flow Over Complex Geometries Using Operator Networks](https://huggingface.co/papers/2512.04434).
* **Includes a direct link to the corresponding GitHub repository**: [https://github.com/baskargroup/TimeDependent-DeepONet](https://github.com/baskargroup/TimeDependent-DeepONet), which provides code for the aforementioned model.
