Let's streamline the deployment process for the VFS Appointment Bot using Docker!
Introduce a Dockerfile to automate the setup and deployment.
Implementation:
1. Create a Dockerfile specifying the base image (e.g., Python), dependencies, environment variables, and bot code.
2. Add clear instructions in the README on building and running the Docker image.

This enhancement would improve the accessibility and maintainability of the VFS Appointment Bot. Let's discuss the specifics of the Dockerfile and implementation details!

@michealch Sure, go ahead with the dockerization :) Else I can work on this as well. (Approved by @ranjan-mohanty)
