Don't execute prefetches for bot user agents (#40435)
Such bots typically navigate websites using hard navigations (as they crawl one URL at a time). Respectively, they do not benefit from prefetches at all, while increasing the cost of both the crawl and operating the site. <!-- Thanks for opening a PR! Your contribution is much appreciated.
