Incorrectly escaped script command

[Tikkoneus]

Hello! My apologies, I'm waaaaay out of my depth so please pardon my ignorance.

When using rails new foobar -j esbuild --css bootstrap to initialize a new rails 7.0.8 app I receive:

Add watch:css script
         run  npm pkg set scripts.watch:css="nodemon --watch ./app/assets/stylesheets/ --ext scss --exec "yarn build:css"" from "."

This appears to be from the nested double quotes. By hand-editing vendor/bundle/ruby/3.2.0/gems/cssbundling-rails-1.3.2/lib/install/bootstrap/install.rb and changing line 25 from: add_package_json_script("watch:css", "nodemon --watch ./app/assets/stylesheets/ --ext scss --exec \"#{bundler_run_cmd } build:css\"", false) to add_package_json_script("watch:css", "nodemon --watch ./app/assets/stylesheets/ --ext scss --exec '#{bundler_run_cmd } build:css'", false) The error goes away. (Changed the escaped double-quotes to single quotes.)
