build(deps): bump dnsruby from 1.61.3 to 1.61.4 in /docs

workflows/tests: cleanup steps.

cmd/tap-info: improve comma usage.

Set up Homebrew should handle both the Git and Ruby setup for us (and
do so faster).

Broken in https://github.com/Homebrew/brew/pull/8230.

Remove more tap pinning code.

This was deprecated and removed a while ago.

Revert "Deprecate global `Homebrew.args`."

workflows/tests: use setup-homebrew GitHub Action.

cask/cmd/upgrade: output cask upgrades on new line

This allows more code reuse.

audit: add --tap argument.

cask/cmd/update: output message consistency

Handle casks in commands more consistently.

This allows auditing a single tap (so is useful for `test-bot`).

- Ensure the usage documentation always mentions casks when appropriate
- Use --formulae or --casks consistently
- Provide --formulae and --casks switches to upgrade
- Mark more switches as conflicting

bump-formula-pr: fix check_all_pull_requests

Deprecate global `Homebrew.args`.

Fix issue where the cask_opts env variable was not respected when running upgrade, reinstall, uninstall

license: permit no license for non-core taps, add exempted license groups
