apacheGH-39003: [CI][macOS] Don't update Homebrew

It's better that we always use the latest Homebrew to check with the
latest Homebrew that are used by most users. But it's difficult to
maintain. So we don't update Homebrew. GitHub hosted GitHub Actions
Runners updates Homebrew periodically. We depend on it.
