This is a major version bump but things were generally straightforward
save two wrinkles:
* it is necessary to ignore collisions in the gitlab bundler
environment as both `omniauth_oauth2_generic` and
`apollo_upload_server` provide a `console` executable.
* grpc had to be patched since its build system expects the `AR`
environment variable to contain not just the path to `ar` but
also the `rpc` flags (see the discussion in nixpkgs #63056).
