Add license and task category

This PR adds the `license` and `task_categories` metadata to the dataset card for better discoverability and clarity. The `task_categories` is set to `text-classification` as the dataset involves classifying research papers based on their safety-related topics and language usage. The license is set to `cc-by-4.0`.

 # The State of Multilingual LLM Safety Research: From Measuring the Language Gap to Mitigating It
-We present a comprehensive analysis of the linguistic diversity of LLM safety research, highlighting the English-centric nature of the field. Through a systematic review of nearly 300 publications from 2020–2024 across major NLP conferences and workshops at ∗ACL, we identify a significant and growing language gap in LLM safety research, with even high-resource non-English languages receiving minimal attention.
