Bug description

Since Prisma 2.8.0 the following schema.prisma configuration doesn't download the binary in Netlify CI. To clarify, a binary is downloaded if you are running it locally.

generator client {
  provider      = "prisma-client-js"
  binaryTargets = ["native"]
}

How to reproduce

1. Deploy this project to netlify https://github.com/divyendu-test/p2-netlify-ci (fulfil the required env var from Netlify UI)
2. It is on Prisma version 2.8.0 or later (I also tried it on the latest dev 2.10.0-dev.55) and the service URL after the first deploy should fail with

   {"errorType":"Error","errorMessage":"\nInvalid `prisma.user.deleteMany()` invocation in\n/var/task/src/functions/index.js:6:21\n\n\n Query engine binary for current platform \"rhel-openssl-1.0.x\" could not be found.\nThis probably happens, because you built Prisma Client on a different platform.\n(Prisma Client looked in \"/var/task/src/node_modules/@prisma/client/runtime/query-engine-rhel-openssl-1.0.x\")\n\nFiles in /var/task/src/node_modules/@prisma/client/runtime:\n\n index.d.ts\n index.js\n index.js.map\n\nYou already added the platform \"native\" to the \"generator\" block\nin the \"schema.prisma\" file as described in https://pris.ly/d/client-generator,\nbut something went wrong.

3. Change the Prisma CLI/Client version to 2.7.0 and re-deploy
4. It should work as expected (please do "clear cache and deploy" from netlify UI)
5. Note that if you have a project that has the binary already, netlify's cache might provide the binary, so please use "clear cache and deploy" for trying out each version

Expected behavior

1. 2.8.0 should also download the required netlify binary if 2.7.0 does.

Additional context

1. The workaround of adding the specific binary works

   generator client {
     provider      = "prisma-client-js"
     binaryTargets = ["native", "rhel-openssl-1.0.x"]
   }

2. A sample SQL/Schema that this can be tried with

   CREATE TABLE "public"."User" (
      "email" text NOT NULL,
      "id" text NOT NULL,
      "name" text,
      PRIMARY KEY ("id")
   );

   datasource db {
     provider = "postgresql"
     url      = env("NETLIFY_BETA_PG_URL")
   } 
   
     generator client {
     provider      = "prisma-client-js"
     binaryTargets = ["native"]
   }
   
   model User {
     id    String  @id @default(cuid())
     email String  @unique
     name  String?
   }

3. DM me for database credentials if you are trying this from within Prisma.
