Tests on the `main` branch fail in GitHub Codespaces

Bug Description

The test session is failing on the main branch:

$ nox -s test

error: 3 targets failed:
    `--lib`
    `--test test_datetime`
    `--test test_pyerr_debug_unformattable`
nox > Command cargo test --no-fail-fast --no-default-features --all-targets failed with exit code 101
nox > Session test failed.

Steps to Reproduce

1. Open the pyo3 repository on GitHub, click the "Code" button (on the right), and click "+" (Create a codespace on main).
2. pip install nox
3. Install Rust (curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh) > Click "Enter" (Proceed with standard installation)
4. . "$HOME/.cargo/env"
5. export RUST_BACKTRACE=1 to include backtrace
6. nox -s test

Additional Info

No response

Start by reproducing the failure with nox -s test in a GitHub Codespace and isolate the --lib, test_datetime, and test_pyerr_debug_unformattable failures from the reported output. Trace the listed failing tests to their implementation and environment assumptions; done means the test session passes on the main branch in Codespaces.
