Take the website's screenshots with one command

composer screenshots runs Pest browser tests in tests/Screenshots, outside
every test suite: fixed demo data under a frozen clock, desktop (MacBook
14, 2x) and phone (iPhone 15 Pro, 3x) in light and dark, each capture
published at once as WebP at two widths into website/img/screenshots.
