Support `@media(hover)` (needed for tailwind `hover:`)

[liaoliao666]

I'm currently using Tailwind and Blitz, and I've discovered that the following doesn't work:

button { class: "hover:bg-amber-500", "home" }

 .hover\:bg-amber-500 {
    &:hover {
      @media (hover: hover) {
        background-color: var(--color-amber-500);
      }
    }
  }
