[Dependency] Remove the version restriction of transformers and diffu…

…ers (#475)

The old version of `diffusers` used a depreciated (now completed
removed) api in `huggingface_hub`. Thus, it's better to keep the
versions up to date to prevent such problems in the future.

The error log in our ci:
```text

Hint: make sure your test modules/packages have valid Python names.
