 #!CommitTicketReference repository="" revision="61711"
 Site Health: Improve page cache detection with added header and refined
 verification logic.

 - Use a more precise regular expression for identifying "HIT" statuses to
 avoid false positives (e.g., "no-hit").
 - Add specific verification logic for Varnish's `X-Varnish` header.
 - Use a `null` value in the header mapping to indicate a header existence
 check, when no callback is supplied.
 - Improve documentation with links for information about certain headers.

 Developed in https://github.com/WordPress/wordpress-develop/pull/10855

 Follow-up to [61355], [54043].
