numbers/search-available.php throws an error on the "pattern" option

[dragonmantank]

When running numbers/search-available.php, it throws the following error:

PHP Fatal error:  Uncaught TypeError: Argument 1 passed to Vonage\Numbers\Filter\AvailableNumbers::setPattern() must be of the type string, int given

The setPattern() method was changed to take a string but the snippet was never updated.

I would like to take a stab at this if you don't mind? Am I understanding correctly that the code snippet search-available.php needs updated to string like so?

/** @var IterableAPICollection $response */
$filter = new AvailableNumbers([
"pattern" => (string) NUMBER_SEARCH_CRITERIA,
"search_pattern" => (int) NUMBER_SEARCH_PATTERN,
"type" => VONAGE_NUMBER_TYPE,
"features" => VONAGE_NUMBER_FEATURES,
]);
