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.

summary:
- adds prettier formatter configuration
- formats the entire repo using prettier, ignoring minified files
(`*.min.css`) and heavy generated html
- changes extensions of all `.html` files to `.liquid`, which is more
correct and necessary for prettier to work correctly
- replaces "%-" and "-%" with just "%" — manual liquid formatting using
minus signs is superfluous since we are compressing and minifying the
code anyway
- adds CI action for running prettier check on PR and pushes to master
