      `rake release` must be invoked from the `Release` GitHub action,
      and must not be invoked locally. This ensures the gem is properly signed
      and distributed by the appropriate user.

      Note that it is the `rubygems/release-gem@v1` step in the `Release`
      action that invokes this task. Do not rename or remove this task, or the
      release-gem step will fail. Reimplement this task with caution.
