Skip pnpm warning about build scripts

[thomasballinger]

Either we need to maintain these lists in each template or do something fancy on install.

Or something simpler on install: just add all the reasonable ones we expect and trust.

Maintaining these in e.g. package.json might look like

  "pnpm": {
    "onlyBuiltDependencies": [
      "esbuild",
      "@tailwindcss/oxide"
    ]
  }

Adding a known list right before installing could work, it doesn't warn if there are extras.
