feat: show icon name near icon data in website

This would be very useful because it would allow users to use CTRL + F, right now you have to click every icon to know what's the icon's name, having the name hidden you can't search icons by name.

Start by locating the website component that renders each icon's data, then run the website and inspect how icons are displayed. Done means each icon shows its name near its existing data so browser find can locate icons by name.
