PaddleOCR 设置text_detection_model_name='PP-OCRv5_server_det', text_recognition_model_name='PP-OCRv5_server_rec'，但实际调用的是PP-OCRv5_mobile_det，PP-OCRv5_mobile_rec

🐛 Bug (问题描述)

当PaddleOCR的构造函数里同时设置了
text_detection_model_name
text_recognition_model_name
lang
需要查看最终调用的模型是否正确，测试显示，会打印
Creating model: ('PP-OCRv5_mobile_det', None)
Using official model (PP-OCRv5_mobile_det), the model files will be automatically downloaded and saved in /home//.paddlex/official_models.
Creating model: ('PP-OCRv5_mobile_rec', None)
Using official model (PP-OCRv5_mobile_rec), the model files will be automatically downloaded and saved in /home//.paddlex/official_models.

原因为https://github.com/PaddlePaddle/PaddleOCR/tree/main/paddleocr/_pipelines/ocr.py
代码里有这样一段
if text_detection_model_dir is None and text_recognition_model_dir is None:
if lang is not None or ocr_version is not None:
det_model_name, rec_model_name = self._get_ocr_model_names(
lang, ocr_version
)
if det_model_name is None or rec_model_name is None:
raise ValueError(
f"No models are available for the language {repr(lang)} and OCR version {repr(ocr_version)}."
)
text_detection_model_name = det_model_name
text_recognition_model_name = rec_model_name
直接把模型给改了。

你好，这几个参数在语义上有些冲突，当同时指定时，行为可能有些违反直觉。感谢你指出这个问题，我们将在代码中增加检查，使代码行为更符合用户期待
