Cloud Save For Minecraft Java

Add cloud save functionality to Minecraft Java Edition. Normally, players need to manually back up their data. However, when players forget to do so and their computer or certain hardware malfunctions—making data unrecoverable or forcing data to be wiped during repairs (such as hard drive damage)—save file loss becomes unavoidable. In such cases, even without a backup, players can still use cloud saves to restore their data. (By the way, my own save file was lost because of hard drive failure and no backup QAQ)
