Animated icons do not respect prefers-reduced-motion

[MHLut]

This is an accessibility bug.

Some pages have animated (or CSS-transitioned) icons used as bullet points or next to CTAs.

Moving images have adverse effects on people with motion disorders.

I checked the pages with prefers-reduced-motion: reduce enabled per macOS settings.

The setting above should have reduced or stopped the animations, but didn't.

Pages affected:

• https://www.djangoproject.com/
• https://www.djangoproject.com/start/overview/
• Every other page that uses animated icons.

(FYI, I am willing to pick this one up myself)
