Add Dockerfile and README.md instructions

[samin-irtiza]

This PR enhances the project by enabling the application to be run as a CLI tool using Docker. Users can now easily analyze codebases and generate tutorials without needing to install dependencies locally.

Key Updates:

• Dockerization:

  • Builds a lightweight runtime image (65.8MB approximately as of now) for the CLI tool using PyInstaller and Docker.
  • Ensures the application binary is executable and ready to use.

• Usage Instructions:

  • Added steps in the README for building and running the Docker container.
  • Users can pass arguments like --repo, --dir, and other CLI options directly to the Dockerized application.

Benefits:

• Simplifies setup and usage by encapsulating the application in a Docker container.
• Provides a consistent runtime environment for the CLI tool.

Users can now run the application with a single Docker command or set up a shell alias for even easier access.
