Change fa_version -> version in wan/distributed/ulysses.py:distributed_attention

which is defined in the wan/modules/attention.py:attention

def attention(
    q,
    k,
    v,
    q_lens=None,
    k_lens=None,
    dropout_p=0.,
    softmax_scale=None,
    q_scale=None,
    causal=False,
    window_size=(-1, -1),
    deterministic=False,
    dtype=torch.bfloat16,
    version=None,  # Not `fa_version`
