public function ZeroConfigPurger::invalidateEverything in Varnish purger 8.2

Invalidate the entire website.

This supports invalidation objects of the type 'everything'. Because many load balancers on Acquia Cloud host multiple websites (e.g. sites in a multisite) this will only affect the current site instance. This works because all Varnish-cached resources are tagged with a unique identifier coming from hostingInfo::getSiteIdentifier().
