Deprecated `shrinkwrap` in `.npmrc`

[MikeMcC399]

Situation

.npmrc includes the configuration:

shrinkwrap=false

This causes a warning:

npm warn config shrinkwrap Use the --package-lock setting instead.

The deprecation is first noted in https://docs.npmjs.com/cli/v7/using-npm/config#shrinkwrap which continues also in https://docs.npmjs.com/cli/v11/using-npm/config#shrinkwrap

shrinkwrap

• Default: true
• Type: Boolean
• DEPRECATED: Use the --package-lock setting instead.

Alias for --package-lock

npm 12 no longer lists shrinkwrap

Steps to reproduce

Ubuntu 24.04.4 LTS, Node.js 20.20.1

git clone pkgjs/action pkgjs-action
cd pkgjs-action
npm install

Logs

Suggestion

Remove shrinkwrap=false from .npmrc. The equivalent package-lock=false is already listed.
