When installing lerna via npm install two warning are being showed about the usage of deprecated functionalities of used modules. This is present in both older version (5.5.2) and on the most recent version (6.5.1)

npm WARN deprecated [email protected]: This functionality has been moved to @npmcli/fs
npm WARN deprecated @npmcli/[email protected]: This functionality has been moved to @npmcli/fs

Expected Behavior

I would prefer the replacement of the deprecated code to avoid potential future issues as soon as possible.

Steps to Reproduce

Create an empty folder and create a package.json file in that folder with the following content.

{
  "name": "test-app",
  "devDependencies": {
    "lerna": "6.5.1"
  }
}

Run npm install and notice the warning message regarding deprecated functionality.
