 {{{
 #!CommitTicketReference repository="" revision="57698"
 General: Handle missing field in WP_List_Util::pluck().

 Handles when the `$field` (i.e. key or property) is missing in one of the
 `$input_list` items by checking the key (array) or property (object)
 exists before using it for assignment.

 Resolves the following bugs:

 * a PHP warning for undefined key|property.
 * `null` being set for that array or object within the returned list.

 The changes resolve the issues in both `WP_List_Util::pluck()` (if invoked
 directly) and `wp_list_pluck()`.

 Also includes an additional test for the scenario where the
 `wp_list_pluck()` `$index_key` is not `null`, the `$field` is missing in
 one of the `$input_list` items.

 Follow-up to [55423], [51663], [42527], [38928].

 Props iamarunchaitanyajami, davidbinda, hellofromTonya, helgatheviking.
 Fixes #59774.
