Add script to generate Play Store screenshot sizes

- Introduced a Node.js script (`playstore-screenshot-sizes.mjs`) to resize images for Play Store screenshots based on predefined profiles (phone, tablet-7, tablet-10).
- The script reads images from a specified input directory, processes them, and saves the resized images in an output directory with appropriate naming conventions.
- Added a Bash wrapper script (`playstore-screenshot-sizes.sh`) to execute the Node.js script easily from the command line.
