Changelog Entry

Fix PDF loader when using default CEE and OCR

Description

Fix PDF loader when using default Content Extraction Engine and OCR enabled

Commit to fixing issues due to incorrect dimension calculation when reshaping images using the Langchain class Pypdfloader.

Using the PyMuPDFLoader call instead of the PyPDFLoader call fixes errors encountered when processing PDF files with images.
