nx-ignore doesn't seem to work on netlify with pnpm

[jaredh159]

trying to use nx-ignore on netlify with an ignore command, but my monorepo is using pnpm, and at the time that netlify runs the ignore script, it can't seem to find nx and errors out:

[...]
12:51:49 PM: ≫ Creating temp folder to install Nx: /tmp/.nx-ignore
12:51:49 PM: /bin/sh: 1: pnpm: not found
12:51:49 PM: ≫ Cannot find installed Nx
