Add Docker and Kubernetes configurations for Responsible AI services

[hasnatelias]

• Created .gitignore to exclude sensitive configuration files.
• Added devenv.md for local development setup instructions using Docker.
• Introduced docker-compose files for Cosmos DB emulator and Responsible AI services.
• Added Kubernetes deployment manifests for all Responsible AI components including MongoDB, backend, admin, explain, fairness, file storage, LLM benchmarking, LLM explain, MFE, model detail, moderation layer, moderation model, privacy, reporting tool, security, and shell services.
• Updated Dockerfiles for each service to ensure proper installation of dependencies and improved debugging output.
• Ensured all services are configured to use environment variables for sensitive information.
