Why

Because Homebrew installation of the beta version doesn't always install the latest beta version due to their interpretation of "latest version" (see Homebrew/homebrew-cask#207869 (comment) and Homebrew/homebrew-cask#214051 (comment)).
And because I want the beta version, at least as long as the terraform plugin isn't merged into stable.

What

The main content of the script is taken from https://github.com/1Password/install-cli-action/blob/main/install-cli.sh 1password cli github action.

How

As part of a personal system_update script (which I run frequently) I run this command after some brew upgrade.
