Improve homepage performance and UX

[sanjana2505006]

I was looking at the homepage and thought we could make a few quick improvements:

• Lazy loading: Currently, all images load at once. Adding lazy loading would help the page load faster initially.
• Smooth scrolling: Clicking anchor links jumps instantly right now. It would feel much nicer if it scrolled smoothly.
• Cleanup: There's also some dead code in index.html (the hidden training section) that we can remove.

I’ve opened a PR addressing these changes. Please let me know if any adjustments are needed

@sanjana2505006 Thank you, after these let's pause on website improvement as a full website Refresh/Redesign will be coming at some point in the future as part of #355. That Refresh/Redesign is prioritized lower than Grails 7, 7.1 and 8.0 work on https://github.com/apache/grails-core which is 95% of the focus on Grails. The website Refresh/Redesign is on hold until there is time to dedicated to the planning process to finalize the approach and approve the design.

@jamesfredley Got it. Thank you for the context and clarification!
I’ll pause on website-related improvements for now. Please do let me know if I can help with the future refresh/redesign or contribute elsewhere in the meantime.

@sanjana2505006 Please also take a look at the other Grails repos https://github.com/apache/?q=grails-&type=all&language=&sort=#org-profile-repositories . There are many open issues spanning documentation to bugs.

Thank you, @jamesfredley! I’ll go through the other Grails repos and try to pick up some issues where I can contribute effectively.
