Make doc search results use <a> tags instead of js for navigating

This has the primary advantage of not interfering with browser default
behavior for links like being able to cmd/ctrl+click on a result to open
the result in a new tab but leave the current page as-is (previous
behavior both opened a new tab and changed the current tab's location to
the result's)
