Unable to setup in a workspace with other package manager

[JounQin]

I want to setup pnpm globally together with other PMs enabled, but I got:

Error: Multiple versions of pnpm specified:
    - version latest in the GitHub Action config with the key "version"
    - version yarn@4.9.2 in the package.json with the key "packageManager"
  Remove one of these versions to avoid version mismatch errors like ERR_PNPM_BAD_PM_VERSION

It's not:

- version latest in the GitHub Action config with the key "version"
- version yarn@4.9.2 in the package.json with the key "packageManager"

The point is, I want to install pnpm globally.

I'm using npm i -g pnpm before corepack enable as workaround now.
