fix: xfail AMPLIFY FSDP2 tests and remove stale ESM2 HF FSDP2 xfail

The AMPLIFY model on HuggingFace Hub (nvidia/AMPLIFY_120M) does not
implement get_input_embeddings(), which accelerate FSDP2 now requires
during model preparation (transformers>=5.6). The previous fix (#1563)
modified a local copy of amplify_te.py, but the test loads the model
from HuggingFace Hub, so the fix had no effect.

Also removes the stale xfail from test_hf_with_fsdp2_config (BIONEMO-3331)
since those ESM2 HF tests now pass with the current container.
