Pull request overview
This PR removes the deprecated experimental_get_query_params and experimental_set_query_params functions, which have been deprecated for over 2 years and replaced by the st.query_params API. The removal is comprehensive, eliminating all implementation code, tests, and tracking mechanisms for the experimental API.
Key Changes:
- Removed the experimental query params implementation module and all related tracking/enforcement code
- Deleted all unit and E2E tests specific to the experimental API
- Updated existing tests to use the current
st.query_paramsAPI - Cleaned up unused imports resulting from the removal
