Github Modernizer

Hi, I decided to scratch my own itch and fix the little things that annoy me on GitHub. What grinds my gears the most is analyzing GitHub Actions logs. It is hard to navigate between test failures. I'm simplifying that by utilizing a default search query and adding keyboard shortcuts to jump between failures. I'm also highlighting currently reviewed file in the file tree, adding tooltips where GitHub clips content and putting failed actions on top of the list (sometimes I have dozens of actions and scrolling to failed ones is a nightmare).
