Message:

General: Validate input of wp_list_pluck().

wp_list_pluck() is used by WordPress to pluck items from a list. Of course, this requires a list. This validates the input of wp_list_pluck() to ensure it is a list.

This matches the behaviour of wp_list_sort() and wp_filter_object_list().

Props marv2, davidbaumwald, mkox, SergeyBiryukov, dd32.
Fixes #54751.
