feat: Add `divide` icons (#568)
Added 3 division icons (also knows as an obelus). One by itself, one with a circle around it, and one with a square around it. These are meant to compliment plus, minus, and x icons.
fix: Adjust dots so that they render in Figma
We use lines with 0 length to represent dots. However, lines with 0 length don't render in Figma. To
workaround this issue, we give those lines a length of 0.01 instead of 0.
