🐛 fix(utils.py): fix try_setting_streaming_options function to correctly set streaming attribute

The try_setting_streaming_options function now correctly sets the streaming attribute of the llm object to True if it is an instance of BaseLanguageModel and has the streaming attribute. This fixes a bug where the streaming attribute was not being set correctly.
