`db push` / `migrate` is hiding the binary download process during `generate`, leading to confusion

Bug description

When you enable Napi and try npx prisma db push --preview-feature the process stuck running the generators.

How to reproduce

1. Enable Napi by adding previewFeatures = ["napi"] to your schema.prisma
2. Run npx prisma db push --preview-feature
3. The process then stuck at: Running generate... (Use --skip-generate to skip the generators)

Expected behavior

Generators finish successful

Thanks, so we should really make sure this is more visible to users and they/you will not be confused about this any more.

@janpio is correct, after remove the node_modules, and run npm install the process was running in the background.

Today I install v2.22.1, and I see a script downloaded already the engine, so this problem will not repeat from new install.
