Zsh completion broken and documentation URLs broken/removed

[knksmith57]

Describe the bug

Before upgrading Copilot CLI today, the following snippet from my ~/.zshrc executed as documented on https://docs.github.com/en/copilot/managing-copilot/configure-personal-settings/configuring-github-copilot-in-the-cli#zsh

if command -v gh &>/dev/null; then
  ## https://docs.github.com/en/copilot/managing-copilot/configure-personal-settings/configuring-github-copilot-in-the-cli#zsh
  eval "$(gh copilot alias -- zsh)"
fi

After upgrading to 0.0.389, I now observe the following error message when launching a new shell:

error: Invalid command format.

Did you mean: copilot -i "zsh"?

For non-interactive mode, use the -p or --prompt option.
Try 'copilot --help' for more information.

It would appear that the alias subcommand has been removed and the documentation has been relocated (or entirely deleted). I can confirm that no shell completion is being automatically wired up behind the scenes—it's entirely missing/broken now.
