PDM cannot correctly import the ssl module after upgrade to Python 3.11.5

[igoforth]

• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

1. Upgrade to Python 3.11.5 and use it as PDM interpreter
2. Run any PDM command that accesses the internet

Actual behavior

short:

/home/kali/.local/share/pdm/venv/lib/python3.11/site-packages/pdm/cli/actions.py:318: RuntimeWarning: Failed to get latest version: Can't connect to HTTPS URL because the SSL module is not available.
  warnings.warn(f"Failed to get latest version: {e}", RuntimeWarning, stacklevel=1)

Expected behavior

PDM correctly imports the ssl module.

See the issue here where Poetry has to be updated:
python/cpython#108525

This has little to do with PDM. Confirm the following:

1. Can you use ssl module in the host interpreter Python 3.11.5?
2. Can you use ssl module in a virtualenv python created with Python 3.11.5? You can create one with virtualenv --python /usr/bin/python3, install the tool if not existing.

It was working fine on a different computer. So I'm going to look into it more and reopen if I discover any relevant problems.
