@knqyf263 I fixed error with docs workflows after update Python to 3.12 (in actions/setup-python@v4).

But after these changes i thought that perhaps we want just lock Python version on 3.11?
Python will support 3.11 until 2027 year -https://devguide.python.org/versions/

installing several dependencies required updating setuptools - https://github.com/aquasecurity/trivy/actions/runs/6663370495/job/18109128951
GitHub also recommends updating setuptools and wheel - https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-python#installing-dependencies

squidfunk/mkdocs-material:9.4.6 (new version) also returns error for PyYAML 6.0.0.
Updated it to avoid conflicts with new PyYAML version other packages after subsequent Python updates.

We'll face the same problem in 2027. It is good to bump Python.
