Description

• The main changes are based on the possible glmnet clone based on our opened issue (Python 3.9 Compatibility civisanalytics/python-glmnet#76).
• Respectively, python v3.8 has been dropped and v3.12 is added.
• CI scripts changed to run test for all supported python versions except python 3.12. Windows, and Mac OS will be added in a separate PR.
• Dependency versions are now more loose w.r.t previous versions.
• Unit-tests are adapted based on the API changes (e.g. Bayesian Optimization or Shap).

Pull Request Checklist

• Added tests for added or changed code.
• Added documentation for changed code.
