 {{{
 #!CommitTicketReference repository="" revision="61172"
 Date/Time: Prevent a PHP exception when inserting posts with a partially
 malformed `post_date`.

 This commit updates `wp_resolve_post_date()` to use a regular expression
 for parsing the date string into year, month, and day matches. This
 approach handles missing leading zeros more reliably than `substr()` while
 remaining performant (see #57683).

 It also adds checks and type-casting to `wp_checkdate()` variables before
 passing them into PHP's `checkdate()` function to avoid the potential for
 a `TypeError` in PHP 8 and newer (see #54186).

 Lastly, it includes 2 new unit tests (with data providers) to cover an
 array of valid and invalid date formats (YYYY-MM-DD, YYYY-MM-DD HH:MM:SS,
 ISO 8601, RSS, leap years, malformed inputs, etc...)

 Props alordiel, desrosj, johnbillion, johnjamesjacoby, johnregan3,

 Fixes #26798.
