docs: enhance documentation structure and clarify repository layout

- Updated the README and various documentation files to reflect the new flat layout of the `gregFramework`, emphasizing the direct placement of repositories like `gregMod.<Name>/` and `gregExt.<Name>/` under `gregFramework/`.
- Added details about the `gregModmanager/` and `gregDataCenterExporter/` directories, clarifying their roles and contents.
- Improved descriptions and links throughout the documentation to ensure consistency and accuracy, enhancing user navigation and understanding of the project structure.
- Adjusted language in several sections to better communicate the purpose and organization of the repositories.

This commit improves the overall clarity and usability of the documentation.
