Update README.md with revised model path and quantization details

Update the example LLaMA model file path to reflect the new naming convention. Clarify support for GGUF format models, specifying full FP16 support and partial support for Q8_0 and Q4_0 quantization.

 ## Current Features & Roadmap
 
-  - **Support for GGUF format models** with Q8_0 and Q4_0 quantization.
+  - **Support for GGUF format models** with full FP16 and partial support for Q8_0 and Q4_0 quantization.
   - **Instruction-following and chat modes** for various use cases.
   - **Interactive CLI** with `--interactive` and `--instruct` modes.
   - **Flexible backend switching** - choose OpenCL or PTX at runtime (need to build TornadoVM with both enabled).
