Upgrade transformers to fix CI (#17823)

Python package pipeline fails due to "tokenizers" compilation. Since
"tokenizers" is a dep of "transformers", we update its version and hope
a new solution had been there.

```
error: casting `&T` to `&mut T` is undefined behavior, even if the reference is unused, consider instead using an `UnsafeCell`
