std docs: enhance search browser history UX
Before this change every keypress in the search field causes a browser history entry, which makes navigating back annoying. On first keypress in the search field, a new history entry is created. On subsequent keypresses, the most recent history entry is replaced. Therefore a typical history after searching and navigating to an entry might look like 1. documentation root 2. search page "print" 3. docs for `std.debug.print` Co-authored-by: Žiga Željko <ziga.zeljko@gmail.com>
