feat(home-hero): replace svg with illustrator code

I exported the SVG code from Illustrator instead of Sketch. Sketch used `transform()` to place individual groups on the SVG canvas, which prevented me from using CSS3 transforms for the page animations.
Illustrator, on the other hand, uses hard-coded x / y coordinates. That lets me use CSS3 transforms for animations without any trouble.
