This happened a few times for me, the latest occurrence is here: https://github.com/nazar-pc/abundance/actions/runs/23842313355/job/69500910852?pr=605

Essentially, the action completed successfully, but cargo-nextest wasn't actually installed in practice.

It should probably error if installation was not possible for whatever reason.
