🚀 feat(config.yaml, base.py): enable RecursiveCharacterTextSplitter and update TextSplitterCreator to handle it

The RecursiveCharacterTextSplitter is now enabled in the config.yaml file. The TextSplitterCreator class in base.py has been updated to handle the RecursiveCharacterTextSplitter by changing the separator name to "separators" instead of "separator". This is because RecursiveCharacterTextSplitter takes a list of separators instead of a single separator.
