fix: update hardcoded paths in utility scripts after book/ restructure

Updated Python utility scripts to use correct paths with book/ prefix:
- rename_downloaded_images.py: quarto/contents/labs → book/quarto/contents/labs
- rename_auto_images.py: quarto/contents/labs → book/quarto/contents/labs
- convert_svg_to_png.py: quarto/contents → book/quarto/contents
- check_self_referential_sections.py: quarto/contents → book/quarto/contents

These scripts are run from the repository root, so they need the full
path including the book/ directory.
