Migrated <GhUnsplashPhoto> to glimmer component
refs https://github.com/TryGhost/Ghost/issues/14101 - extracted the ratio zoom handling to a `{{ratio-zoom}}` modifier to clean up the component and avoid needing lifecycle hooks that don't exist in Glimmer components - disabled `no-nested-interactive` linting in the template - not ideal but we'd need a much bigger design refactor to eliminate the nested links
