Bump pyyaml from 6.0 to 6.0.1

…penrouter.ai)

This commit includes several changes to the `Coder` class in `coder.py` to improve how models are handled.

1. The import statement has been updated to include the `os` module. This allows us to access environment variables.
2. The method for setting the `tiktoken_model_name` has been updated to handle non-OpenAI models. For these models, the name is set to gpt-4 as a default.
3. The `get_llm_model_name` method now checks for an environment variable `AICODEBOT_LLM_MODEL`. If this variable is set, its value is used as the model name.
4. The `get_token_length` method has been updated to strip leading and trailing whitespace from the `short_text` variable.
5. The `model_options` dictionary in the `get_llm_model_name` method now includes the anthropic/claude-2 model.

These changes should make the `Coder` class more flexible and robust when dealing with different models. 🚀
