Hi! I've verified that StrOutputParser is indeed missing from the Output Parsers section in the LangChain Core reference docs. I'd like to work on adding it. Could a maintainer confirm this is the right approach?

After investigation, the reference page at reference.langchain.com is auto-generated from the Python source and is not built from this docs repo (confirmed in README.md). The fix likely needs to go into langchain-core/output_parsers/__init__.py in the main langchain repo. Could a maintainer confirm the right approach?
