This patch enables descriptions on the CLI completion script. It used to be disabled due to the CLI historically not supporting cobra v2 completions, as seen by this patch https://github.com/docker/cli/commit/cbec75e2f3f5afd3334db693829a6b150612076c. As an escape hatch, the user can set the `DOCKER_CLI_DISABLE_COMPLETION_DESCRIPTION` environment variable to disable the completion description when generating the completion file with `docker completion <fish|bash|zsh>`.
