changed LambdaFilter/LambdaTokenizer phpdoc param from function to callable

[ghost]

Hello, I am using your library for some time and I think it is great!
But, every time I pass a callable in LambdaFilter, psalm and phpstorm arguing at me that I'm using an invalid argument like this:

ERROR: InvalidArgument - scripts/Namespace/VO/SomeVO.php:42:52 - Argument 1 of TextAnalysis\Filters\LambdaFilter::__construct expects TextAnalysis\Filters\function, pure-Closure(mixed):(null|string) provided (see https://psalm.dev/004) ->applyTransformation(new LambdaFilter(static function (string $word) { return preg_replace(self::AVAILABLE_CHARACTERS_REGEXP, '', $word); }));

Maybe it would be better to have callable phpdoc, because it doesn't lead to any errors?
