Pin google-protobuf to non-buggy version

[tlund101]

Description

google-protobuf@3.21.4 introduces a bug that results in secrets (and possibly other data) coming back as undefined via GRPC. This PR is a demo that adds an E2E test case and pins the google-protobuf version to a working version.

If you want to see the test fail, just unpin the library version and rebuild the lock file. I was not able to narrow down where in the protobuf library the issue is due to build issues, but I created issues in this repo as a stopgap and FYI. I figured a maintainer here may have a better insight as to where the problem lay.
