When Corepack is installed from the npm registry with

npm install -g corepack

then Corepack should not be automatically enabled for pnpm and Yarn.

Why is this needed?

In a situation where Corepack is needed for Yarn and not wanted for pnpm, automatically enabling Corepack for pnpm breaks local workflows that expect pnpm to have been installed with npm install -g pnpm. Installing Corepack overrides this. Due to #112 it is not possible to simply execute corepack disable pnpm because Corepack does not restore the original state.
