CI: Use Python 3.9 for PyLint presubmit action
CI: Use Python 3.9 for PyLint presubmit action

 - Use Python 3.9 instead of Python 3.8 for PyLint presubmit action.
 - Update the setup-python action to v2, which is actively maintained.
 - Parse the Python version as a string ("3.9" instead of 3.9), since otherwise  Python 3.10 will be rounded and processed as Python 3.1.
