Comment (by hellofromTonya):

 Dropping [51968] as a reminder of ongoing architectural decisions needed
 to resolve remaining known deprecation notices

 This changeset ignores (on purpose) "null to nullable" deprecations for
 select tests. Why? Here are the details:

 Adds an expectation for PHP 8.1 "passing null to non-nullable" deprecation
 notice to select tests where the deprecation is generated by one of the
 functions in the wp-`includes/formatting.php` file, either via a filter
 hook callback or by a direct call.

 Instead of haphazardly fixing these issues exposed by the tests, a more
 structural and all-encompassing solution for input validation should be
 architected and implemented as otherwise, we'll keep running into similar
 issues time and again with each new PHP version.

 To discourage people from "fixing" these issues now anyway, this commit
 "hides" nearly all of these issues from the test runs.

 Once a more structural solution is designed, these tests and the
 underlying functions causing the deprecation notices should be revisited
 and the structural solution put in place.
