Feature Request: Implement Smooth Scrolling

[ShubhamOulkar]

Description

Currently, scrolling between sections or anchor links on the page is abrupt and not user-friendly. This feature request proposes implementing smooth scrolling behavior across the application to improve user experience and visual flow.

Expected Behavior

• When navigating to anchors (e.g., #section-id), the scroll should transition smoothly.
• Applicable to both in-page navigation and programmatic scrolling.

We have this for the top link, although this logic can be handled in CSS and applied globally like I did in #1562 (https://github.com/bjohansebas/expressjs.com-fork/blob/7bc18069ce58ea47b2f9645de8552615b4cc828f/css/style.css#L15). If you want, you can bring that logic into a new PR :)
