fix: Clarify llama model prompt-format help text

Browse source 
Updates the help text for the `llama model prompt-format` command
to clarify that users should provide a specific model name
(e.g., Llama3.1-8B, Llama3.2-11B-Vision), not a model family.
Removes the default value and field for `--model-name` to prevent users from
mistakenly thinking a model family name is acceptable.
Adds guidance to run `llama model list` to view valid model names.
