Add Docker and Docker Compose workflow for Synthea

[sauravkumarsahoo]

Created a Docker and Docker Compose based workflow to simplify synthetic patient data generation using a container to manage and abstract all dependencies, and allow end-users to focus of running the container with specified .env to get their desired outputs directly.

Summary

• add a multi-stage Dockerfile to build and run Synthea in containers
• add docker-entrypoint support for env-driven generation settings and output formats
• add compose.yaml and .env.example for local Docker Compose runs
• document Docker and Compose usage in README
• ensure version.txt is generated before processing resources

Notes

• local .env is intentionally not included in this PR

Pull request overview

Adds a containerized workflow for running Synthea locally via Docker/Docker Compose, including an env-driven entrypoint and documentation updates. This fits the repo by providing a reproducible runtime and build path for generating artifacts without requiring a local Java/Gradle setup.

Changes:

• Add a multi-stage Dockerfile that builds the shaded Synthea JAR and runs it via an entrypoint script.
• Add docker-entrypoint.sh to translate env vars into Synthea CLI/config flags (including output format toggles).
• Add compose.yaml, .env.example, and README instructions for local Compose-based runs; ensure version.txt exists before resource processing.
