This PR aims to improve the organization and readability of our example documents used in unit tests, specifically focusing on PDF and image files. ### Summary - Created two new subdirectories in the `example-docs` folder: - `pdf/`: for all PDF example files - `img/`: for all image example files - Moved relevant PDF files from `example-docs/` to `example-docs/pdf/` - Moved relevant image files from `example-docs/` to `example-docs/img/` - Updated file paths in affected unit & ingest tests to reflect the new directory structure ### Testing All unit & ingest tests should be updated and verified to work with the new file structure. ## Notes Other file types (e.g., office documents, HTML files) remain in the root of `example-docs/` for now. ## Next Steps Consider similar reorganization for other file types if this structure proves to be beneficial. --------- Co-authored-by: ryannikolaidis <1208590+ryannikolaidis@users.noreply.github.com> Co-authored-by: christinestraub <christinestraub@users.noreply.github.com>
