Pin huggingface_hub in more places (#15403)

### Summary
We need to pin huggingface_hub in CI to avoid an incompatibility with
our pinned version of transformers. See
#15399 for more context - I
missed a few places on trunk jobs. Cleaning these up here.

### Test Plan
Running with ciflow/trunk. I verified that the
test-huggingface-transformers-macos / * and gemma3-4b macos jobs pass on
this PR. They are failing on trunk (see
https://hud.pytorch.org/pytorch/executorch/commit/4c30da308ee811bdfa44fd4bea3bc439bfd303d4
for an example).
