User Story Title: Containerize the Microservice Using Docker

[ShirishGaikwad]

As a developer, I want to containerize the accounts microservice using Docker, So that I can ensure consistent deployment across different environments.

Acceptance Criteria:

Create a Dockerfile for the accounts microservice. Build and test the Docker image locally. Document the containerization process. Ensure the containerized service runs as expected.
