fix test-huggingface-transformers-* tests (#14752)

Fix these tests
https://hud.pytorch.org/hud/pytorch/executorch/main/1?per_page=50&name_filter=huggingface-transformer

The optimum is installed in a bit weird way, inside executorch folder,
it clone optimum inside executorch, and try to install executorch in the
nested optimum folder. Install optimum via pip instead in the same
commit. The behavior should be the same, tests still run as expected
