binaryTargets with native regression

[divyenduz]

Prisma generate for the following config fails with a 404.

generator photon {
  provider = "photonjs"
  binaryTargets = ["native"]
}

On catalina, the error is different but the link from the "Downloading" message is still a 404.

Fixed in latest alpha. We'll shortly release a patch for this.
