Intermittent CI failures related to unpacking packages #14079
Description
We get intermittent failures in CI during the "pyright: Run test cases" step. The failure is always consistent between all three platform this test runs on, and also look consistent within a PR, but the packages it affects are different between PRs. The affected packages have no new releases.
Example from https://github.com/python/typeshed/actions/runs/15062531917/job/42340224286?pr=14078
