Add `audio-text-to-text` task category

This PR adds the `audio-text-to-text` task category to the dataset card metadata. This category better reflects the dataset's purpose of evaluating speech language models on audio reasoning tasks, such as Sentence Stress Reasoning (SSR) and Sentence Stress Detection (SSD), which involve processing audio input to derive text-based interpretations. This addition will improve the dataset's discoverability for researchers working in this domain.

The existing paper links have been retained as per the instructions regarding arXiv links.
