Expected behavior
CI to pass, and contributors not to suffer.

Screenshots
N/A

Versions:

• pvlib.__version__: latest
• python: 3.9 to 3.11

Additional context
Problem comes from the setup-python action, this issue has already been reported there: actions/setup-python#942

Strangely, this has only been reported for v5, thou we are still using v4.

I suggest we wait until it gets resolved upstream, to avoid making changes that may affect the other versions and, once it gets fixed in setup-python, that our patch becomes a problem.

This issue has been solved, I suppose it was a problem related to some GH provider. No actions are deemed necessary on this repo.
