for context, deserialize the json into Node classes from: https://gist.github.com/UmarZein/4c46bc42323d0f61bd3494dec48f3fa4
the difference between this dataset and https://huggingface.co/datasets/umarzein/wikipedia-headings-20k is that this one is
more compact i.e.: the column rootwards is distinct so it saves space but you have to parse the json first
