Polish The Copy Confetti On The Icons Page (#5191)

- Say "Copied SVG!" and "Copied name!" when an icon is copied with
  Shift + click or Ctrl/Cmd + click.
- Center the text over the icon instead of starting at its left edge.
- Give the icon the brand border while the confetti plays.
- Keep the confetti visible when reduced motion is on; the site-wide
  reduced-motion rule shrank it to 0.01ms so it never showed.
