Code Review

This pull request updates the stream processing documentation in both English and Chinese by removing previous restrictions on User-defined functions (UDFs) and the Windows platform. A review comment identifies that the Chinese documentation is missing certain restrictions still present in the English version, specifically regarding the DELETE_OUTPUT_TABLE option and the Cast function in state window triggers, and provides a suggestion to restore consistency.

[gemini-code-assist]

The Chinese documentation is missing several temporary restrictions that are still present in the English version. To maintain consistency and ensure users are aware of all current limitations, please add the missing items for DELETE_OUTPUT_TABLE and the Cast function in state window triggers, following the order in the English documentation.
