chore: Add Qwen2.5 and Phi3.5 to Readme (#265)

## Summary
Qwen2.5 was released recently - it uses the same model architecture as
Qwen2 (see:
https://huggingface.co/Qwen/Qwen2.5-7B/blob/main/config.json#L3).
Likewise for Phi3.5 (see:
https://huggingface.co/microsoft/Phi-3.5-mini-instruct/blob/main/config.json#L4).
Also, the `model_type`s in the above configs will allow
AutoLigerKernelForCausalLM to work correctly for these models out of the
box.

Adding them to the readme for clarity / marketing reasons :)

- Hardware Type: <BLANK>
- [ x ] run `make test` to ensure correctness
- [ x ] run `make checkstyle` to ensure code style
- [ x ] run `make test-convergence` to ensure convergence
