Build fails as additional dependencies aren't being picked up.

• Railpack shows an example of adding mise dependences RAILPACK_PACKAGES="node bun@latest python@3.10"https://railpack.com/guides/installing-packages

• Protobuf compiler is a mise tool https://mise.jdx.dev/registry.html?filter=protoc#tools

• Setting RAILPACK_PACKAGES="protoc" the build fails and it does not seem to be recognized ```[Region: us-east4]
