Tests on the `main` branch fail in GitHub Codespaces

[olp-cs]

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

Taking a quick look at this, seems that the default Python interpreter on GitHub codespaces is statically linked. We don't support static linking very well, #416 is pretty longstanding.

I think we might want to consider refusing to statically link libpython and instead refer users to PyOxidizer (and/or how to get a dynamically linked Python interpreter).
