Fix: Hyphenate to "model-in-the-loop"

The phrase "model-in-the-loop" is now hyphenated to align with standard practices in technical literature, where hyphenation of compound adjectives clarifies their function as a single descriptor.

-**Segment Anything Model 2 (SAM 2)** is a foundation model towards solving promptable visual segmentation in images and videos. We extend SAM to video by considering images as a video with a single frame. The model design is a simple transformer architecture with streaming memory for real-time video processing. We build a model in the loop data engine, which improves model and data via user interaction, to collect [**our SA-V dataset**](https://ai.meta.com/datasets/segment-anything-video), the largest video segmentation dataset to date. SAM 2 trained on our data provides strong performance across a wide range of tasks and visual domains.
