Follwup for "Support workspaces from package.json"

@zkochan #2255

I have some valid feedback on the subject. pnpm pkg doesn't have npm pkg that is very good when you want to read/write/delete in multiple package.json files.
https://docs.npmjs.com/cli/v9/commands/npm-pkg

I know that you can write pnpm -r exec npm pkg get version but the output is not the same and not JSON parsable.

I rather define workspaces in one place and not have to maintain two places like package.json and pnpm-workspace.yaml.

> npm pkg get name version --ws

{
  "hello": {
    "name": "hello",
    "version": "0.0.1"
  },
  "world": {
    "name": "world",
    "version": "1.0.0"
  }
}

vs

> pnpm -r exec npm pkg get name version

{
  "name": "hello",
  "version": "0.0.1"
}
{
  "name": "world",
  "version": "1.0.0"
}
