Update how horizontal scrollbars work for code and tables

For consistency across browsers and systems, set the overflow-x to auto, but using colors that match the background of the code block or table, so the scrollbar isn’t initially visible. On hover, the colors will change to the defined scrollbar colors. Note they do still display differently depending on each user’s systems settings, based on if they use classic or overlay scrollbars
Also moved scrollbar-related code to that section of the CSS file
