The new cobra v1.2.0 release brings a number of bug fixes for shell completion scripts. Regenerate the scripts with `make completions` to sync them with the upstream version, currently we have some custom ones to avoid some upstream bugs. Because the new cobra version has all fixes we should use the upstream scripts. Add a check to CI to ensure we always use the up to date scripts.
