feat: Add Copy Button to Documentation Code Snippets

[dipanshurdev]

Issue

The documentation currently lacks a copy button next to code snippets, which would make it easier for users to copy the code quickly. This feature is common in many technical docs and helps avoid issues like accidentally missing characters when copying.

Reproduce

• Add a small copy button next to each <pre> or <code> block in the docs.
• This button, when clicked, should copy the code to the clipboard.
