Dropped Platform/Runtime Support

As agreed on during the last Power Grid Model meet-up and as outlined in the Release Strategy, support for the following platforms and runtimes were dropped. Please ensure your environment meets the new minimum requirements.

Python 3.11 support (see also this announcement). Please refer to our Release Strategy for details.
