New-YamlHelp needs to convert the module.md file to YAML

[sdwheeler]

Summary of the new feature / enhancement

In the current reference pipeline, they are converting the module.md file to YAML. Since the intent is for the OPS pipeline to replace the existing code with New-YamlHelp, we need to convert the module file to YAML.

Proposed technical implementation details (optional)

The OPS pipeline has a well-defined schema for this already. We should target that schema.
