Bug Report: <BUG> cimg/python:3.12.6 breaks our builds

[BenSandeen]

Describe the bug
cimg/python:3.12.6 broke our CircleCI builds, specifically breaking pip package installation

To Reproduce
The failing build step is defined as follows:

      - run:
          name: install python dependencies
          command: |
            python -m pip install --upgrade pip
            python -m pip install pipenv --user
            pipenv install

This is our Pipfile:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
ansible = "*"
ansible-lint = "*"
boto3 = "*"
credstash = "*"
cryptography = "*"
six = "*"
yamllint = "*"
wheel = "*"
awscli = "*"

[dev-packages]

[requires]
python_version = "3.12"

With cimg/python:3.12.6, we get the following output for the Python package installation step:

Expected behavior
Install Python packages successfully

Workarounds
Specifying 3.12.5 avoids this issue
