Update task category to 'other' and license to 'cc-by-nc-4.0'

This PR updates the metadata to align with the provided instructions and the terms of use stated within the dataset card:

- Changed `task_categories` to `other` as specified by the task requirements.
- Corrected the `license` from `apache-2.0` to `cc-by-nc-4.0`. The existing dataset card explicitly states that the dataset is "intended solely for **academic research purposes**," which is consistent with a non-commercial license like `cc-by-nc-4.0`.

No further changes were made to the content sections, as they are comprehensive and well-structured, including all necessary links, abstract, sample usage, and citation.
