[Bug]: yarn -C ignores package.json packageManager setting.

Self-service

• I'd be willing to implement a fix

Describe the bug

calling yarn with -C causes the package.json file to be ignored w/ respect to the version of yarn to use.

I ran into this building from a systemd service and using -C to specify the working directory.

To reproduce

cd dir && yarn set version 4.2.2 && yarn --version
4.2.2

cd ..; yarn -C "$(pwd)/dir" --version
yarn run v1.22.22
