const packageUrl = `https://github.com/cli/cli/releases/download/v${version}/gh_${version}_${platform}_amd64.tar.gz`

Hello there, I'm using this action in self-hosted runners and one of the usage is to run with macOS, but this line in the action hardcodes the format to be tar.gz, whereas, github.com/cli/cli 's releases page, the archive format is zip for macos, would you be open to a PR that'll take the zip format as an input and that will default to .tar.gz so that it's not a breaking change?
