Bump google.golang.org/genproto to latest

[usrme]

Change Summary

What and Why:

This upgrades google.golang.org/genproto to the latest available version to avoid "ambiguous import" errors as described here, which causes issues when trying to build the project currently at the tip:

$ make build
Running Generate for Help and GraphQL client
go generate ./...
