This commit allows themes to define up to 2 screenshots in about.json. These should be paths within the theme's git repository, images with a 1MB max file size and max width 3840x2160. These screenshots will be downloaded and stored against a theme field, and we will use these in the redesigned theme grid UI. These screenshots will be updated when the theme is updated in the same way the additional theme files are. For now this is gated behind a hidden `theme_download_screenshots` site setting, to allow us to test this on a small number of sites without making other sites make unnecessary uploads. **Future considerations:** * We may want to have a specialized naming system for screenshots. E.g. having light.png/dark.png/some_palette.png * We may want to show more than one screenshot for the theme, maybe in a carousel or reacting to dark mode or color palette changes * We may want to allow clicking on the theme screenshot to show a lightbox * We may want to make an optimized thumbnail image for the theme grid --------- Co-authored-by: Ted Johansson <ted@discourse.org>
