docs: Update README.md with correct PyTorch version and dependencies

Updates:
- Change PyTorch version from 2.9.0 to 2.2.0 in Dependencies section
- Add missing packages: accelerate, huggingface-hub, spaces
- Update Tech Stack section to reflect ZeroGPU-compatible PyTorch
- Add inline comment about ZeroGPU compatibility

Dependencies List Now Shows:
- gradio==5.49.1
- transformers==4.57.1
- torch==2.2.0 (ZeroGPU compatible)
- safetensors==0.6.2
- accelerate==0.26.1
- sentencepiece==0.2.0
- protobuf==4.25.1
- huggingface-hub>=0.19.0
- python-dotenv==1.0.0
- spaces (ZeroGPU support)

Consistency:
- README.md dependencies now match requirements.txt
- All version numbers accurate and up-to-date
- ZeroGPU compatibility clearly documented
