Refactor command class names to be consistent

[caendesilva]

Abstract

Currently, class names, especially commands, are not very consistent. Refactoring this will allow the code to be more readable and easier to maintain.

Commands

I propose the format Hyde + CommandDescriptor + Command

Here are the commands, including already valid commands:
├── BasePublishingCommand.php
├── BuildStaticSiteCommand.php
├── Debug.php
├── HydePublishConfigsCommand.php
├── HydePublishHomepageCommand.php
├── HydePublishViewsCommand.php
├── MakePostCommand.php
├── MakeValidatorCommand.php
├── PublishStubsCommand.php
└── Validate.php
