Correct ONNX model library metadata to PaddleOCR

This ONNX repository declares library_name: transformers, while its documented loading path uses PaddleOCR with ONNX Runtime. It contains inference.onnx and inference.yml rather than a Transformers model package.

Change library_name to PaddleOCR so the Hub uses the matching library integration and download-counting rule, which explicitly includes the root inference.onnx file. All other metadata and model card content are preserved.
