🐛 Describe the bug

The llama.meta.com / ... / meta-llama-guard-2/ docs includes the <|begin_of_text|> text/tokens in it's usage ;

The current inference/prompt_format_utils.py code does not use this for Llama Guard 2.

Should these beginning tokens be or not used for Llama Guard 2?

Error logs

No error.

Expected behavior

Documentation matches code utils.
