[ENHANCEMENT]: Make the scrollbars on Docs website better

Hi,

Since contributing here, I saw the docs having the default scrollbars that looked bad

<img width="2158" height="1716" alt="Image" src="https://github.com/user-attachments/assets/df7aef38-bf44-4105-b921-5fd7e1f53907" />

Linking the PR to make it better and match the aesthetic of the website.

Thanks
