Håkon Hægland bd402ee230 Fix auto-detection by not setting PYTHON_VERSIONS when not specified ...

The auto-detection wasn't working because the
CLI was always setting PYTHON_VERSIONS environment variable to all supported
versions when --python-versions was not provided.

Changes:
- click_helpers.py: Return None instead of all versions when option not provided
- helpers.py: Only set PYTHON_VERSIONS env var when explicitly specified
- main.py: Update type hints to allow None for python_versions parameter

Now the flow works correctly:
1. No --python-versions CLI option -> python_versions = None
2. None passed to Docker -> no PYTHON_VERSIONS env var set
3. Container auto-detects installed versions using pyenv
4. Tests run only on detected versions
