ImportError: cannot import name 'builder' from 'google.protobuf.internal'

I updated the googlefonts-project-template for my [Fragment Mono](https://github.com/weiweihuanghuang/fragment-mono) repo and now when I try to `make build` locally, I get the follwoing error:

```
▶ make build
rm -rf fonts
(for config in sources/config*.yaml; do . venv/bin/activate; gftools builder $config; done) && touch build.stamp
