chore: update package-lock.json (#2997)

* chore: update `package-lock.json`

When running `npm ci`, we get the following error:

```
npm error `npm ci` can only install packages when your package.json and package-lock.json or npm-shrinkwrap.json are in sync. Please update your lock file with `npm install` before continuing.
npm error
npm error Missing: @aws-cdk/[email protected] from lock file
npm error Missing: @aws-cdk/[email protected] from lock file
npm error Missing: @aws-cdk/[email protected] from lock file
npm error Missing: [email protected] from lock file
npm error Missing: [email protected] from lock file
npm error Missing: [email protected] from lock file
npm error Missing: [email protected] from lock file
npm error Missing: @aws-cdk/[email protected] from lock file
npm error Missing: @isaacs/[email protected] from lock file
npm error Missing: @isaacs/[email protected] from lock file
```

This indicates that the lockfile is not really being used, which feels
dangerous.

We need to hunt down why the build succeeds everywhere even though the
lockfile is not used (probably means we use `npm install` everywhere
instead of `npm ci`), but this is at least a first step.
