Add Copy-to-Clipboard Functionality for Code Blocks in Documentation

[Shrikantgiri25]

Hi maintainers,

I’d like to propose a documentation-only improvement to enhance usability: adding a “Copy” button to code blocks. This allows users to quickly copy example code without modifying the DRF library or API.

A simple implementation using CSS and JavaScript can achieve this, and it can be integrated via mkdocs.yml without affecting functionality.

Screenshot attached below for reference.

This change aligns with the current focus on documentation improvements. I’m happy to submit a PR if the maintainers support this enhancement.
