tox: Without making change to our CI, all environments created from cache now failing for any commit.

Issue

Without making change to our CI, all environments created using tox were failing for every commit. After we limited the version of tox 3.28.0, then we can pass CI. This is a temporary solution. We would appreciate some advice so we don’t have to limit tox versions within our CI. Our repo is open source and at https://github.com/Qiskit/qiskit-metal

Environment

This is happening in github actions, not locally. https://github.com/Qiskit/qiskit-metal/blob/main/.github/workflows/main.yml

Provide at least:

• OS:
• pip list of the host Python where tox is installed: We tried on Ubuntu 20.04 passed, mac-os -latest passed

Not on command line, but in github actions. 

Output of running tox

Provide the output of tox -rvv:

Minimal example

If possible, provide a minimal reproducer for the issue: We can’t run github actions locally, so sorry that we can’t provide this. However, we would appreciate your support.
