Issue with current documentation:

Hi team,

I noticed that one of the links in the LangChain.js documentation is broken. It points to a page that no longer exists.

Details:

• Broken link: https://langchain-ai.github.io/langgraphjs/https%3A/docs.langchain.com/oss/javascript/langgraph/quickstart
• Where it appears: https://js.langchain.com/docs/introduction/
• Section: Tutorials
• Expected behavior: The link should open the relevant page or redirect to the updated documentation.
• Actual behavior: The link returns a 404 (page not found).

---

Steps to Reproduce:

1. Visit: https://js.langchain.com/docs/introduction/
2. Click on: LangGraph.js quickstart
3. See error (404 or missing page).

---

Suggested Fix:

• Update the link to the correct documentation page (if it has moved).
• If the section was removed, consider deleting or replacing the outdated link.
