Update requirements.txt

**Description**

I encounter the following error when running locally.
I just realize that `transformers` has a breaking changes since version `4.25.0` (Dec 2, 2022) (https://pypi.org/project/transformers/#history)

```

```

To fix this problem, simply install `transformers==4.24.0`
