building and preview broken without esbuild from version ? 1.6

[shadoof]

For build and preview (after npm update) I have had to add a devDependencies to my package.json:

{
  "dependencies": {
    "@observablehq/notebook-kit": "^2.1.3"
  },
  "scripts": {
    "preview": "notebooks preview --root nbks --template nbks/template.md",
    "build": "notebooks build --root nbks --out ../docs -- nbks/*.html"
  },
  "devDependencies": {
    "esbuild": "^0.28.0"
  }
}

Thanks for the report. I will investigate.
