Message:

Date/Time: Cast extracted strings to integers in wp_resolve_post_date().

wp_resolve_post_date() extracts year/month/day from a post date (which is a string) and passes it to wp_checkdate (and from there to checkdate()), which requires ints.

Casting the strings to integers avoids PHP notices due to incorrect argument types.

Props hilayt24.
Fixes #54186
