_wp_ajax_menu_quick_search: Deprecated taxonomy input for get_terms

[birgire]

In _wp_ajax_menu_quick_search() the taxonomy input is deprecated since 4.5.

The taxonomy input for get_terms() should now be part of the argument array.

See e.g.

​https://developer.wordpress.org/reference/functions/get_terms/

So we need to change:

$terms = get_terms( $matches[2], array(
    'name__like' => $query,
    'number' => 10,
));

in https://core.trac.wordpress.org/browser/tags/4.9.8/src/wp-admin/includes/nav-menu.php#L109

to

$terms = get_terms(
    array(
        'taxonomy'   => $matches[2],
        'name__like' => $query,
        'number'     => 10,
    )
);

In 44686:

Menus: Fix a deprecated call to get_terms().

The taxonomy should be passed as part of $args, rather than as its own argument.

Props birgire.
Fixes #45297.
