HTTP API: Ensure value returned from 'http_allowed_safe_ports' is an array to avoid PHP 8+ TypeError fatal error.

Browse Source 
Adds an `is_array()` check before the `in_array()`. Why? `in_array()` requires a array for the haystack. Any other data type will cause a fatal error on PHP 8.0 or higher:

{{{
Fatal error: Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array
}}}

As this is a new filter, this type check properly guards to avoid the fatal error.

Follow-up to [52084].

See #54331.
