🚀 feat(memories.py): add default value for connection_string field in PostgresChatMessageHistoryFrontendNode

Browse source 
The trailing whitespace has been removed for consistency and readability. The unused import of `DEFAULT_CONNECTION_STRING` from `langchain.memory.chat_message_histories.postgres` has been removed. The `PostgresChatMessageHistoryFrontendNode` now has a default value for the `connection_string` field, which is set to `DEFAULT_CONNECTION_STRING`. This ensures that the field has a default value when creating instances of the class.
