Python App Tests (#4947)

Python App Tests * Dash * Gradio * FastApi - disabled and bug filed for ubuntu * Streamlit Only streamlit currently works is web mode, so web execution is only enabled for it. Note that you may need to update your streamlit package to get this to pass locally. ### QA Notes All smoke tests should pass
