Correcting Transformers Translation Doc Example

I found an oversight when I was running through the transformers translation examples, wanted to let you know how to fix.

Correction:

Specify model

In the pytorch example of collating the data, either specify the model beforehand:

model = "t5-small"
data_collator = DataCollatorForSeq2Seq(tokenizer=tokenizer, model=model)

or more precise:

data_collator = DataCollatorForSeq2Seq(tokenizer=tokenizer, model="t5-small")
