Hi team,

This PR aims to improve the model card for microsoft/Phi-4-mini-flash-reasoning by adding the paper's abstract directly into the Markdown content. This provides users with a more immediate and comprehensive understanding of the model's research context and contributions without needing to click through to external links.

The current model card already includes links to the paper and the GitHub repository, as well as clear sample usage and correct metadata. This change focuses on enriching the "paper" information as specified in our model card guidelines.

Please let me know if any adjustments are needed!
Thanks,
Niels
