Coding Standards: Cast wp_count_terms() result to int before usin…

…g in `ceil()`.

This addresses two instances of the (numeric string) return value from `wp_count_terms()` being used directly in `ceil()`, which expects an `int|float`.

Affected methods:
* `WP_Sitemaps_Taxonomies::get_max_num_pages()`
* `wp_nav_menu_item_taxonomy_meta_box()`

Reference: [https://www.php.net/manual/en/function.ceil.php PHP Manual: ceil()].

Follow-up to [14248], [14291], [14569], [14943], [48072], [57648].
