Updated special_tokens_map.json and tokenizer_config.json

In the standard LLaMA 3 `special_tokens_map.json` and `tokenizer_config.json` the eos token is set to `<|end_of_text|>`. This leads to model spamming `assistant` into chat, not stopping and chatting with itself.

This fix changes the eos token to `<|eot_id|>` in `special_tokens_map.json` and `tokenizer_config.json`, so the model can work with standard settings.
