pnpmStorePath = execSync("pnpm store path", { encoding: "utf8" });

currently takes a very naive approach to check if pnpm is installed
if on windows and theres multiple drives, and the store is on a different drive and an alias has been added to the pnpm path on the other drive then this will fail
