Improve model card for Lego-Edit: Add metadata, links, abstract, and structure

This pull request significantly enhances the model card for the `Lego-Edit` framework by:

- **Updating metadata**:
- Changing the `license` to `cc-by-nc-4.0` to reflect the model's licensing terms as specified in the GitHub repository's disclaimer.
- Adding `pipeline_tag: image-to-image` to improve discoverability for image editing and manipulation tasks.
- Adding `library_name: transformers` based on evidence of `Qwen2_5_VLForConditionalGeneration` architecture, `Qwen2Tokenizer`, `Qwen2_5_VLProcessor`, and explicit mention of `transformers` library modification in the quick start guide.
- **Adding key links**: Including direct links to the paper, project page, and GitHub repository for easy access to related resources.
- **Incorporating abstract**: Providing the paper's abstract to give a quick overview of the model's purpose and methodology.
- **Restructuring content**: Reorganizing the model card for better readability, integrating images directly from the GitHub repository, and adding sections for Features, Disclaimer, Citation, and Acknowledgments from the official GitHub README.
- **Removing verbose file information**: As per instructions, the detailed file content has been removed from the model card.

For detailed setup and usage instructions, please refer to the provided GitHub repository.

+## Abstract
+Instruction-based image editing has garnered significant attention due to its direct interaction with users. However, real-world user instructions are immensely diverse, and existing methods often fail to generalize effectively to instructions outside their training domain, limiting their practical application. To address this, we propose Lego-Edit, which leverages the generalization capability of Multi-modal Large Language Model (MLLM) to organize a suite of model-level editing tools to tackle this challenge. Lego-Edit incorporates two key designs: (1) a model-level toolkit comprising diverse models efficiently trained on limited data and several image manipulation functions, enabling fine-grained composition of editing actions by the MLLM; and (2) a three-stage progressive reinforcement learning approach that uses feedback on unannotated, open-domain instructions to train the MLLM, equipping it with generalized reasoning capabilities for handling real-world instructions. Experiments demonstrate that Lego-Edit achieves state-of-the-art performance on GEdit-Bench and ImgBench. It exhibits robust reasoning capabilities for open-domain instructions and can utilize newly introduced editing tools without additional fine-tuning. The figure below showcases Lego-Edit's qualitative performance.

+
+## ✨ Features
+
+Lego-Edit supports local editing, global editing, and multi-step editing as demonstrated in our tests, with corresponding results shown above. We discuss its feedback responsiveness and tool-extension capabilities in our paper.
+
+Additionally, Lego-Edit accepts mask inputs for precise editing region control. Example applications are provided here:

+You can try it and find more usages of this framework.
+
+## 🔥 Quick Start
+
+For detailed instructions on setting up the environment, downloading checkpoints, and running the Gradio WebUI, please refer to the [Quick Start section in the GitHub repository](https://github.com/xiaomi-research/lego-edit#--quick-start).
+
+## 💼 New Tools Integration
+
+Lego-Edit supports the integration of new tools. For guidance on how to add custom tools and make them usable by The Builder, please refer to the [New Tools Integration section in the GitHub repository](https://github.com/xiaomi-research/lego-edit#--new-tools-integration).
+
+## 📍 More Usages
+
+Some editing models are trained at a resolution of 768 via the ICEdit method. The corresponding trained [Single-Task-LoRA](https://huggingface.co/xiaomi-research/lego-edit/tree/main/loras) are provided. For independent usage of these LoRAs, refer to the usage instructions at [ICEdit](https://github.com/River-Zhang/ICEdit).
