Differentiate between TW and JP client when detecting an existing installation

[BuIlDaLiBlE]

Due to TW and JP client having the same GameRegistryName: 崩壊3rd the launcher detection of JP when TW is installed and vice versa is janky. This needs to be handled in a special way that doesn't rely on GameRegistryName alone. I'm leaving this issue here to remind myself about this issue since I'll not be working on it because it's a low priority.
