Refactor SVG processing scripts and add new functionality

- Updated `svg-cleanup.js` to improve SVG file processing and validation.
- Refactored `update-data.js` to streamline the data update process and integrate new scripts for generating image variants and syncing data files.
- Introduced `generate-variants.js` to handle the conversion of SVG files to PNG and JPG formats.
- Created `sync-data.js` to synchronize logo data with the filesystem, ensuring accurate representation of available images.
- Enhanced error handling and logging throughout the scripts for better debugging and user feedback.
- Added support for processing all collections or a specific collection based on command-line arguments or environment variables.
