Attempt to install bundler fails

I have a CI system that runs Ruby tests via bazel inside a docker image, with a dedicated image per bazel version + ruby version that we support.

The docker image is built with the desired bazel version, and ruby is installed via RVM at docker image build time along with the version of `bundler` we use to generate our `Gemfile.lock`.

The following error is observed in the [PR](https://github.com/protocolbuffers/protobuf/pull/19808) where I'm attempting to adopt `rules_ruby`, which indicates that `rules_ruby` is trying to install `bundler-2.4.22` despite it being installed already. It fails, presumably because of bazel sandbox rules.

Is there something I need to do differently to prevent `rules_ruby` from attempting the installation? Does gem installation ever work when using the `system` version and if not, should disabling automatic installation of `bundler` be disabled in this configuration?
