Revert "Merge pull request #34387 from yhirano55/rails_info_properties_json"

We had a discussion on the Core team and we don't want to expose this information
as a JSON endpoint and not by default.

It doesn't make sense to expose this JSON locally and this controller is only
accessible in dev, so the proposed access from a production app seems off.

This reverts commit 8eaffe7e89719ac62ff29c2e4208cfbeb1cd1c38, reversing
changes made to b6e4305c3bca4c673996d0af9db0f4cfbf50215e.
