Subject: [PATCH] fix: add sharp dependency for image processing and improve
 ocr (#9554)

build: add sharp dependency for image processing

* Added sharp as a dependency in package.json to enhance image processing capabilities.
* Removed sharp from the devDependencies section.
* Refactored OCR image preprocessing by integrating grayscale and normalization directly into the process, improving overall efficiency.
