Refactor Dockerfile and add linguist module

This commit refactors the Dockerfile to:
- Reintroduce the programmer user creation with sudo privileges
- Add necessary system dependencies for development tools
- Update Go installation to include PATH in root's bashrc
- Install github-linguist gem

It also includes the addition of a new linguist command module with functions to interact with GitHub Linguist for language statistics and file information retrieval.
