Review and update reference documentation for the modules

Prerequisites

• Accepted Idea: Proposals in this project are created based on ideas that have been marked as Accepted in their Discussion. Before you file an issue for a feature or change, create a discussion. If you file an issue without a discussion, the team may convert it into one.
• Existing Issue: Search the existing issues and discussions for this repository. If there is an issue or discussion that fits your needs do not file a new one. Subscribe, react, or comment on that issue or discussion instead.
• Descriptive Title: Write the title for this issue as a short synopsis. If possible, provide context. For example, "Add Get-Foo cmdlet to Documentarian module" instead of "New cmdlet."

Module

Documentarian, Documentarian.DevX, Documentarian.MarkdownLint, Documentarian.MicrosoftDocs, Documentarian.ModuleAuthor, Documentarian.Vale

Summary

As a user, I want up-to-date reference documentation for the commands, classes, and enums that a module exports, so that I can understand what they do and how I can use them.

Details

We need to go through each of the modules and ensure that the reference documentation for their public code is fully documented.

Start by reviewing the six listed modules—Documentarian, Documentarian.DevX, Documentarian.MarkdownLint, Documentarian.MicrosoftDocs, Documentarian.ModuleAuthor, and Documentarian.Vale—and their existing reference documentation. Identify exported commands, classes, and enums that lack complete documentation; done means the public code in every listed module has up-to-date reference documentation.
