### Snowpark Python API updates

#### New Features

- Added `DataFrame.to_polars()` to convert a Snowpark DataFrame to a Polars DataFrame or LazyFrame.

#### Improvements

- Removed the `experimental` tag from all AI SQL functions in `DataFrameAIFunctions` (`complete`, `filter`, `agg`, `classify`, `similarity`, `sentiment`, `embed`, `summarize_agg`, `transcribe`, `parse_document`, `extract`, `count_tokens`, `split_text_markdown_header`, `split_text_recursive_character`) and `RelationalGroupedDataFrame.ai_agg`.
