Pin huggingface-hub to <=1.13.0

huggingface-hub is a dependency in datasets
that is pinned to <2.0 which huging-face has not
reach yet. That means it will currently always get
the latest version.

After the 1.14.0 update on 6/5-2026, many jobs
have started to time out when downloading using
huggingface-hub.

Pinning in requirements-examples.txt should be
enough, since those requirements should be installed
unless install_executorch.sh is ran with --minimal
