Improve error handling

[cdoko]

Currently, when the bos_token_id or eos_token_id field is missing from generation_config.json, the error message is "Error(missing field bos_token_id`", line: 4, column: 1)", which does not provide clear context about the source of the issue.

This change indicates the problem is in the generation_config.json file.

Thanks for the PR! Can you please also add this logic to the vision pipeline (i.e. vision.rs)?

[cdoko]

I've added the logic to the vision pipeline as requested, and additionally to the ggml and gguf pipelines.
