Add default value to the @param tag for the constructor in /wp-admin/includes/class-custom-image-header.php

[faisalahammad]

WordPress coding standard recommends adding default values to the @param tag for functions that have default values for parameters. In the /wp-admin/includes/class-custom-image-header.php file, the constructor function has a parameter named $admin_image_div_callback, but there is no default value mentioned in the @param tag.

I added "Default false" to the @param tag for the $admin_image_div_callback parameter, so that it is clear to developers that this parameter is optional and its default value is false.

Trac ticket: 58049

@faisalahammad I've added a review to the PR, looks like we need to change $admin_image_div_callback parameter, but another parameter was updated in the code.
