Changed package manager for install-native.mjs to pnpm (#52971)

fixes #52970

Yarn 3 has removed the "--force" flag. This can cause issues with building the Next.js repository if Yarn 3 is activated on a development machine (specifically the postinstall script "install-native.mjs"). Using pnpm as the package manager fixes this issue.
