fix: Path does not end with the package name (#8560)

fix #8558

The @isaacs/cliui package depends on string-width-cjs@4.2.3, but the
package that's actually downloaded is string-width@4.2.3. The name in
the path doesn't match the original name, which is causing an error.
Fix solution: Truncate based on scope depth, not by name.

```
"string-width-cjs": {
          "from": "string-width",
          "version": "4.2.3",
          "resolved": "https://registry.npmjs.org/string-width/-/string-width-4.2.3.tgz",
          "description": "Get the visual width of a string - the number of columns required to display it",
          "license": "MIT",
          "author": {
            "name": "Sindre Sorhus",
            "email": "sindresorhus@gmail.com",
            "url": "sindresorhus.com"
          },
          "homepage": "https://github.com/sindresorhus/string-width#readme",
          "repository": "git+https://github.com/sindresorhus/string-width.git",
          "path": "/Users/beyondkmp/Code/deepFocus/node_modules/.pnpm/string-width@4.2.3/node_modules/string-width",
}                 
                             
```
