Switch from black / pylint to ruff

[bhirsz]

The king is dead, long live.. Recently, ruff tool received a lot of popularity and is often replacing tools that were used so far - black, pylint, flake, isort.. . It offers wide variety of rules, suprising performance and is user friendly. It is already supported by many biggest Python repositories, such as Airflow.

We would like to switch from existing tooling to ruff. It includes:

• updating the documentation
• update precommits
• update lint stage in github ci
• fix any issue found by formatter or linter in the repository
