✨ Added IndexNow to notify search engines of content changes (#28519)

IndexNow lets Ghost notify search engines as soon as a post is
published or updated, rather than waiting for crawlers to rediscover
the change, so new and edited content gets indexed faster across the
participating engines (Bing, Yandex, Seznam, Naver, and others). It
ran as a private developer experiment, proved reliable in production,
and is now on by default for every site.

It respects existing privacy controls: the
config.isPrivacyDisabled('useIndexNow') gate and the is_private site
check both suppress pings where appropriate.
