Fix PHP 8 type error in search category location filter when directory type is string

[Arafat-plugins]

PR Type

What kind of change does this PR introduce?
This PR fixes a PHP 8+ TypeError that occurs when the _directory_type term meta is stored as a scalar string and used in search_category_location_filter().

Currently, get_term_meta( $term->term_id, '_directory_type', true ) can return a string like '191', but later is passed directly to: in_array( $settings['listing_type'], $directory_type );
