Deprecation notice on PHP 8.4

middleland/src/Dispatcher.php

Line 35 in 4848543

public function __construct(array $middleware, ContainerInterface $container = null)

The line

public function __construct(array $middleware, ContainerInterface $container = null)

needs to be

public function __construct(array $middleware, ?ContainerInterface $container = null)

Thanks!
I cannot install PHP 8 in my computer (long story). Do you mind to create a PR with these changes?
And if you update also the tests, it would be great.
