Harden Runner breaks `medyagh/setup-minikube`

[tippmar-nr]

I'm not sure where the problem lies, but there's some odd interaction between the harden-runner action and medyagh/setup-minikube.

If I add harden-runner with egress-policy: audit, the setup-minikube step doesn't fully install and configure Minikube.

A sample workflow run showing the with and without behavior is available here: https://github.com/tippmar-nr/testing/actions/runs/9210727454 -- with harden-runner, the job runs for several minutes and emits a lot of odd messages, before finally failing because Minikube isn't running correctly. Without harden-runner, the job runs for just a couple of minutes and behaves exactly as it should.

Would appreciate any guidance or troubleshooting tips. Thanks!
