set-script has been removed from npm 9

[jcoyne]

Add build script
         run  npm set-script build "esbuild app/javascript/*.* --bundle --sourcemap --outdir=app/assets/builds --public-path=assets" from "."
Unknown command: "set-script"

npm --version
9.0.0

It is used here:

jsbundling-rails/lib/install/esbuild/install.rb

Line 10 in 5e6758f

run %(npm set-script build "#{build_script}")

The below should work in the console

$ npm pkg set scripts.build="webpack --config webpack.config.js"

Should be a simple fix in the code base:

Replace

run %(npm set-script build "#{build_script}")

with

run %(npm pkg set scripts.build="#{build_script}")
