Were you able to get this to work?
Hey!
I've just created this account to share a working version of the python script.
This one solves the html bulk operation problem and also avoids possible charset problems on windows computers.
I changed it so it doesn't take any arguments.Just put the script in the same folder with your html files from Google Keep(from Takeout). Run it with python3. It will create an enex file within the same folder.
Just like with the other one shared in this thread, you might need to install parsedatetime with most probably a command like pip3 install parsedatetime

I exported over 800 notes using this script (and Joplin Desktop).
Hope it works for you too.
