Add paper link to dataset card

This PR improves the dataset card by adding a direct link to the associated paper, [Microsurgical Instrument Segmentation for Robot-Assisted Surgery](https://huggingface.co/papers/2509.11727), at the top of the content.

This enhances discoverability for researchers and provides immediate access to the publication. As per guidelines, the existing arXiv URL in the BibTeX citation has been retained.

 # MISAW-Seg: Pixel-level Surgical Tool Segmentation in Microsurgical Anastomosis
 
+This dataset was presented in the paper: [Microsurgical Instrument Segmentation for Robot-Assisted Surgery](https://huggingface.co/papers/2509.11727).

 ## Dataset Overview
 
 *MISAW-Seg* is a surgical segmentation dataset that extends the original [MISAW dataset](https://www.synapse.org/Synapse:syn21776936/files/) by introducing segmentation annotations for microsurgical tools involved in artificial vessel anastomosis tasks. The original dataset included kinematic data, workflow annotations, and stereo video recordings, but lacked pixel-wise annotations for surgical tools.
