Feature request

From https://php.watch/versions/8.2/partially-supported-callable-deprecation:

PHP 8.2 deprecates certain patterns of callables that do not work with the $callable() pattern.

For example, https://phpstan.org/r/0abbdab0-be93-4efe-9ddf-413f33731ecf should report the deprecated use of 'self::upper' as a callback.

Did PHPStan help you today? Did it make you happy in any way?

PHPStan helps me every day by catching all sorts of other problems, including PHP and Drupal deprecations. It just missed this one.
