Feature Request: Add "Copy Page as Markdown" Button to Nuxt UI v3 Documentation

Description:
Add a button to each component documentation page that allows users to copy the current page content in markdown format.

Problem:

• The full documentation text at ui.nuxt.com/llms-full.txt contains too much information when I only need documentation for specific components
• GitHub raw files don't show the dynamic content visible on the actual documentation site
• Need an easy way to copy specific component documentation for use in prompts to AI assistants

Proposed Solution:
Add a "Copy Page as Markdown" button to each documentation page, similar to the implementation on https://modelcontextprotocol.io/introduction

User Benefit:
This feature would let users easily copy specific component documentation to paste as additional context in AI prompts, improving the relevance and focus of AI assistance for Nuxt UI development.

@Mat4m0 I've already thought about it, and I think it would be a good addition personally, but it would clearly be something that would even be beneficial directly in the nuxt-llms module.
Having an option to also generate a file per page! @farnabaz, is this something that could be considered and not too complex to implement 🤔
