docs:fixed typo (or old documentation) in ipynb tutorial 3 (#3033)

* Update Tutorial3_Basic_QA_Pipeline_without_Elasticsearch.ipynb

Just fixed the key in the document dictionary format so `write_documents()` won't raise an error. By the way the `write_documents()` error is really explicative

* Run convert_notebooks_into_webpages.py
