style: preparing actinia for Pylint 3.x with ruff

[neteler]

Preparing the repo for Pylint 3.x

Motivation

In the GRASS GIS project the Pylint configuration is created from scratch. In preparation for that, the entire Python code is updated with ruff (https://docs.astral.sh/ruff/, an extremely fast Python linter) to comply with Pylint 3 rules.

Steps

Here the respective steps to which might be applied to the actinia-* repos as well.
