DOC: API reference doesn't mention the “messages” stream mode in stream_mode definition.

[habib-source]

Issue with current documentation:

stream_mode (Optional[Union[StreamMode, list[StreamMode]]], default: None ) – The mode to stream output, defaults to self.stream_mode. Options are 'values', 'updates', and 'debug'. values: Emit the current values of the state for each step. updates: Emit only the updates to the state for each step. Output is a dict with the node name as key and the updated values as value. debug: Emit debug events for each step.

For example, this is the definition of stream_mode in the async meth under the CompiledStateGraph url with mention for 'values', 'updates', and 'debug' but no 'messages'. I thought it was deprecated or something. But I tried it out and it works.

Idea or request for content:

add the 'messages' stream mode and it's definition to the stream_mode definition.
