Update Point.php

Right now this lib throws:

> Return type of Grimzy\LaravelMysqlSpatial\Types\Point::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in xxx/vendor/grimzy/laravel-mysql-spatial/src/Types/Point.php on line 95

Fixes grimzy#182
