ENH: Upgrade Python and other packages

[ant0nsc]

• Upgrade to Python 3.9 as a minimum
• Upgrade pillow because of security alerts. This required some API changes and update of test result images
• The behaviour of the LogCaptureFixture changed, requiring changes from logging.info to logger.info
• Downgraded black from 23 to 22 because of version constraints
• Changes in calls to WorkflowParams because of mypy issues that were not detected until now
• hi-ml-azure now also has its own minimal Conda dev environment

Thanks for the monumental effort in handling all the version conflicts and breaking changes! I assume it's all working now based on the tests, and the code changes LGTM.
