Hitchwiki/hitchhiking-rides-dataset · Update dataset card: Add paper/project links, time-series-forecasting task, and BibTeX

This pull request aims to enhance the dataset card for the "Hitchhiking Rides Dataset" by implementing the following improvements:

Update Task Category: Changed the task_categories metadata tag from tabular-regression to time-series-forecasting. This better reflects the dataset's primary use case in predicting waiting times, as highlighted in the paper and the dataset's "Data Science Uses" section.
Add Paper Link: Corrected the empty links to the associated paper, pointing them to the official Hugging Face Papers page: https://huggingface.co/papers/2506.21946.
Add Project Page Link: Included a prominent link to the project's official website (https://tillwenke.github.io/) in the dataset card content for easier access to related resources.
Add BibTeX Citation: Provided a complete BibTeX citation for the paper in the "Citation" section, ensuring proper attribution for researchers.
Minor Correction: Corrected a typo from "scrip" to "script" in the "Dataset Sources" section.

These updates will make the dataset card more informative, accurate, and user-friendly for the community.
