Fix missing requirements.txt in Docker build process

[sonole]

• Added requirements.txt to the Docker build context to resolve the missing file error during the Sphinxsetup.sh script execution.
• Updated Dockerfile to ensure requirements.txt is copied into the working directory before running the script.
• Verified successful Docker image build with all dependencies installed.

This change resolves the error:

ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'
