Python virtual env to use in GH actions

[dsimansk]

          Let's open an issue to properly investigate this for all python deps? Options are:

• use break-system-packages flag as a workaround
• use virtual env
• use system package manager or pipx

The issues popped up in knative/community Peribolos check, but we have a couple more of places that uses Python tools. That can have the same symptoms.

Related to GH runner update of python package: actions/runner-images#8615

Some of the options:

Use --break-system-packages

pip install strictyaml --break-system-packages

Pin Python version to previous one:

    - uses: actions/setup-python@v5
      with:
        python-version: "3.11"    
    - run: pip install strictyaml

Init the full virtual env?
