I want to use the v2 CLI with zsh command completion. I tried to follow the [instructions](https://github.com/aws/aws-cli/tree/v2?tab=readme-ov-file#command-completion), but they seem incorrect. The `aws_zsh_completer.sh` file does not exist in the downloaded zip file, nor in `/usr/local/aws-cli/v2/current/`. How does one set up zsh completions?
