Subject: [PATCH] fix: Support webp images in 3MF thumbnail generation

Updated the regex in `get3MFImages` IPC handler in `main.js` to include the `.webp` extension. This ensures that webp images are correctly identified and extracted when generating thumbnails for 3MF files, both in the Metadata directory and throughout the archive. The search is recursive as it iterates over all files in the zip archive.
