A user in Discord recently tried to run the auto-generate script to create completions from `<command> --help` and had issues. In examining the scripts, I found that they used `build-string`, which was deprecated and removed over 2 years ago. In order to prevent future confusion until (and if) these files are updated, I'm moving them to a `needs-update` directory in the repo. Any other outdated files can be moved there as well.
