only one file these days

1.Add two new buttons

·Button 1: Whether to generate roads. This determines if roads will appear in this world type, which is friendly for those who don't want to drive on a straight highway (in the future, road types that branch out in various directions will be added, which should be fun, but not in the next version).
·Button 2: Biome distribution pattern, with two options: 'Random Distribution' and 'Along Z-Axis Only'. The former is intended for those who don't select roads or the future branching roads (though it actually works for both), while the latter is for those who want roads (just like in those travel games, keeping the original intention).

2.fix some bugs like language and button visible
