Testing docs in a bazel module requires C++ compiler to build protobuf due to stardoc dependency

When I test docs in rules_oci it fails unless I have a C++ compiler configured on my windows system.
Once I have provided one testing docs takes several minutes whilst protobuf is compiled.
Can the tool that is being built be simplified so that it does not require so much time & local tooling just to validate some docs?

Start by reproducing the documentation test for rules_oci on Windows and tracing the stardoc dependency that builds protobuf. The work is complete when documentation validation no longer requires a configured C++ compiler and avoids the current several-minute protobuf compilation.
