Not detecting yarn berry correctly

[fisker]

Description

Use yarn berry without packageManager field, the yarn.lock will be detected, and use the legacy yarn command, and throws

× Error: Command failed with exit code 1: yarn config get registry
Usage Error: Couldn't find a configuration settings named "registry"

Steps to reproduce

1. yarn init -y
2. yarn set version berry
3. yarn
4. np

Expected behavior

Use correct yarn berry config.

Environment

np - 10.0.6
Node.js - 22.4.0
npm - 4.2.2
Git - git version 2.42.0.windows.2
OS - Windows 10

Possible solution is switch to check .yarnrc.yml instead or check yarn.lock but run yarn --version then check version number.
