ModuleNotFoundError for http package when using pip after setup

[silv-io]

Description:
When using pip to, e.g., install setuptools after running the action, we sometimes (but not always) get a ModuleNotFoundError: No module named 'http' error.
This doesn't happen always, and a re-run of the GitHub action usually resolves this error.
The error happens inside urllib, and is also filed there: urllib3/urllib3#3558 where they referred to the action.

Action version:
v5

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted (buildjet-2vcpu-ubuntu-2204)

Tools version:

Python 3.11

Repro steps:
A description with steps to reproduce the issue. If your have a public example or repo to share, please provide the link.

      - name: Set up Python
        uses: actions/setup-python@v5
        with:
          python-version: '3.11'

      - name: Install docker helper dependencies
        run: pip install --upgrade setuptools setuptools_scm

Expected behavior:

This should always work without issue.

Actual behavior:

Sometimes (but not always) we get the following error:
