zero embedding for token_id == `1` (<BOS>)

WARNING : This model and its 68M sibling have ALL ZEROS EMBEDDING for token_id==1 (<BOS>). This creates confusion in measuring StatisCache sequence length. The transformers maintainers chose to detect it based on non-zero cache values, but the all-zeros embedding distorts the get_seq_length(). No blame here, just a combination of design decisions with unpredictable results.
