Sergey Biryukov ccbd16fef1 Media: Check the return type of _get_cron_array() in WP_Media_List_Table::prepare_items().
The following warnings could, in very select circumstances, be shown:
{{{
// PHP 8.0 and higher:
Warning: foreach() argument must be of type array|object, bool given

// PHP 5.6 – 7.4
Warning: Invalid argument supplied for foreach()
}}}

In `WP_Media_List_Table::prepare_items()`, the cron info array is retrieved via a call to `_get_cron_array()`, but as the documentation (correctly) states, the return type of that function is `array|false`, where `false` is returned for a virgin site, with no cron jobs scheduled yet.

However, no type check is done on the return value, and the method just blindly continues by using it in a `foreach`.

Fixed by adding validation for the returned value from `_get_cron_array()` and only running the `foreach` when the returned value is an array.

Reference: [https://developer.wordpress.org/reference/functions/_get_cron_array/ WordPress Developer Resources: _get_cron_array()]

Follow-up to [48417].
