If you are having problems running update_docs perhaps you can try using the codespace:

they are pre-configured mostly

You may have to run this command in the container

apt-get install npm

(I made a PR to add this explicitly to the container here #17019)

@Adez017 this document is autogenerated by the ./dev/update_function_docs.sh script which runs separate rust console app to gather documentation from scalar functions documentation methods and creates an md file on top of that.

Do you see any issues with the tool?
