refactor: update project branding and structure for gregFramework

- Changed project title and tagline in docusaurus.config.js to reflect the new branding.
- Updated package.json and package-lock.json to rename the project to gregwiki-docs-site.
- Adjusted sidebar and documentation files to align with the new project structure and naming conventions.
- Enhanced documentation content for clarity and consistency across various sections.
- Added Prettier as a development dependency for code formatting.

This commit aligns the project with the new branding and improves overall documentation quality.
