Support for pnpm

[UtkarshVerma]

Currently, Hugo looks for the npx binary to execute PostCSS commands. In my case, I prefer using pnpm to save time and disk space. Would it be possible to add support for pnpx to Hugo, which is the pnpm counterpart for npx?

I haven't looked into it too much but I've recently been running into JsBuild errors while trying to use pnpm:

Cannot read file "node_modules/some-module": Incorrect function

But it seems to work as expected when using npm.
