Hi guys, was just reading the Document

Hi guys, was just reading the Document Management page (https://docs.llamaindex.ai/en/stable/module_guides/indexing/document_management.html) and the linked notebook file can't be accessed (https://github.com/run-llama/llama_index/blob/main/examples/paul_graham_essay/InsertDemo.ipynb), unless the branch is changed (for example, https://github.com/run-llama/llama_index/blob/8147-bug-streaming-on-react-chat-agent-not-working-as-expected/examples/paul_graham_essay/InsertDemo.ipynb). Just wanted to mention it in in case this was not intentional or if anyone needed access to the notebook.
