Visual Regression Testing with Apify and AI Vision Model

Part A. Generate Base Images Before we can run our visual regression tests, we must generate a series of base screenshots to compare against. This part of the workflow uses an external website screenshotting service, [Apify.com](https://www.apify.com?fpr=414q6), to achieve this. This part of the workflow should only be run when we want to update our base screenshots.
