mPLUG/GUI-Owl-7B · Improve model card: Add pipeline tag, library name, update paper link, and add project page

This PR enhances the model card for GUI-Owl-7B by:

Adding the pipeline_tag: image-text-to-text to improve discoverability on the Hugging Face Hub, as the model is a visual language model capable of multimodal GUI automation.
Specifying library_name: transformers to enable the automated "how to use" code snippet, as the model's config.json indicates compatibility with the transformers library (e.g., Qwen2_5_VLForConditionalGeneration, Qwen2Tokenizer, Qwen2_5_VLProcessor).
Updating the "Paper" link to the official Hugging Face Papers page: Mobile-Agent-v3: Foundamental Agents for GUI Automation.
Adding a "Project Page" link: https://osatlas.github.io/, which was identified in the associated GitHub repository's README.

These updates will make the model more accessible, discoverable, and user-friendly for the community.
