[py] Ignore devtools during linting

[cgoldberg]

User description

Motivation and Context

This PR updates the linting configuration for Python.

After you run build target //py:local_dev, generated Python source files are copied to selenium/webdriver/common/devtools. When you try to run linting after that (by building //py:lint or running tox -e linting), it fails with all sorts of linting violations in the devtools files.

I don't think we care or want to fix violations in these files, so this change just ignores them.

Changes made:

• Exclude the selenium/webdriver/common/devtools directory in linting tool configurations (black, flake8, docformatter).

• Updates Python version to 3.9 in linting tool section of pyproject.toml for isort and black. This was previously set to Python 3.8, but the minimum supported version is Python 3.9 (I'm not sure this change actually affects anything)

I tested locally by running go py:local_dev then ./go py:lint and tox -c py/tox.ini -e linting.
