Current workaround is:

• Provide older python version in your pipeline
• Set setup_python: "false" in the ansible-lint pipeline stpe.

      - uses: actions/setup-python@v6
        with:
          python-version: '3.12'
      # Ansible-lint requires a .git directory to exist in order to function properly.
      # This is a workaround to create an empty .git directory.
      - name: 'Prepare env'
        run: |
          mkdir -p ansible/.git
      - name: 'ansible lint'
        uses: ansible/ansible-lint@main
        with:
          working_directory: ansible
          setup_python: "false"
          args: ""

This is a regression introduced in 7290982 by defaulting to a Python version that no (released) ansible-core version supports
