Dockerfiles: Updated file paths following repo restructuring

Adjusted the file paths in the Dockerfiles to align with the recent repository restructuring. This ensures that the Docker images now correctly reference the files in their new locations.

This change was necessary to maintain consistency and compatibility with the updated repository structure. It ensures that the Docker images can be built successfully and reflects the latest organization of project files.
