Fixes # (issue)

ONNX [Multinomial](https://github.com/onnx/onnx/blob/main/docs/Operators.md#multinomial) operator only supports one input. The sample_size is only an attribute. It should be known when creating/exporting the ONNX model. torch.onnx.export fails with an error.

Comments:
_The documentation is not available anymore as the PR was closed or merged._

You're free to do this on your own to have the model work with ONNX, but this is not the kind of fix we can merge into Transformers as it will hurt every user on other hardware.

I am not intending to merge this PR. I agree that this is a hack not a fix. The reason to create this PR is only to share that change(s) with the other teams I am working with.
