Fix missing sft parameters across distill pipeline

[vlad-karp]

Description

The most recent refactoring of the distill pipeline which combined teacher and student model calls into a single jitted function left some of the sft mode input parameters missing in the distill pipeline.
This is a fix to bring them back

Tests

The same as in #3332.
We probably need a dedicated sft test but that would require refactoring train_distill() to extract labels_fn() to be used for testing.
