Summary

rush-pnpm outdated does not work (prints nothing).

Repro steps

Run rush-pnpm outdated.

Expected result: Outdated dependencies

Actual result: Crickets

Details

As noted elsewhere, pnpm outdated -r -C common/temp does work, but this requires us to have pnpm installed globally. Ideally, we should be using rush for everything, and Rush should be managing pnpm for us and shielding us from that.
