Broken links in docs pages

[benjamincburns]

The "Annotations" link under the "Schema" heading on the Low Level LangGraph Concepts docs page leads to the following URL, which 404s: https://langchain-ai.github.io/langgraphjs/reference/functions/langgraph.Annotation-1.html

I can't recall any other specific links that are broken like this, but I feel like I've encountered others as well. Do you guys happen to have broken link monitoring set up for your docs? If not, I'd recommend it, as this sort of thing can degrade devs' impressions of the quality of the library/framework.
