ci: fix redacted HOMEBREW_GITHUB_TOKEN env value

The previous commit had a literal '***' placeholder where the GitHub
Actions expression ${{ secrets.HOMEBREW_GITHUB_TOKEN }} should have
been. The workflow couldn't parse, so runs showed as 'failure' with
zero jobs and the display name fell back to the file path.

Fixed by writing the correct expression directly.
