Our score went down a little bit after the last few changes. Avoiding
lazy loading some images (as introduced in #2183), since [it is strongly
recommended to omit hero images and other images or iframes that are
likely to appear above the fold from being
lazy-loaded](https://web.dev/articles/browser-level-lazy-loading-for-cmss#avoid_lazy_loading_above-the-fold_elements).
Also added missing `alt` to google scholar field.
