Add torchao to FP8 error message by jphme · Pull Request #3514 · huggingface/accelerate

What does this PR do?

When trying to get FP8 training to work, i was confused by the error message (as the docs say that FP8 via torchao is supported as well).
is_fp8_available tests for all 3 FP8 methods, so the error message should also state all FP8 options :).
