Add multi-GPU support for Docker deployments

- Created separate docker-compose override files for different GPU types:
  - docker-compose.nvidia.yml for NVIDIA GPUs
  - docker-compose.amd.yml for AMD GPUs with ROCm
  - docker-compose.apple.yml for Apple Silicon
- Updated README with GPU-specific Docker configurations
- Updated deployment instructions to use appropriate override files
- Added detailed configurations for each GPU type including:
  - Device mappings and drivers
  - Environment variables
  - Platform specifications
  - Memory and resource limits

This allows users to easily deploy Talk2Me with their specific GPU hardware.
