There is a conflicting dependency in apache-airflow 2.3.0
- apache-airflow 1.23.0 -> rich '12.3.0' -> typing-extensions (>=4.0.0,<5.0); python_version < "3.9"
- kfp 1.8.12 -> typing-extensions (<4,>=3.7.4); python_version < "3.9"

This issue will be resolved when kfp releases a new version because kfp already changed the cap in https://github.com/kubeflow/pipelines/pull/7632.
