node package has yarn.lock and package-lock.json

There should probably only be 1, which package manager do you prefer?

I don't really care which one, tbh I don't know what 90% of the files there are for as they have been autogenerated at some point. Feel free to remove anything that isn't needed. If it builds with "yarn build" then the file is probably not needed.
