ImmersiveMC

This quick release fixes a couple issues introduced with ImmersiveMC 1.6.0 Alpha 3:

• For all Minecraft versions, fixed the chest lid changes crashing on dedicated servers. Whoops!
• Fixed the ender chest not making sounds when opened or closed immersively.
• For 26.1.2 (and future Minecraft versions), added world upgrading for worlds carried over from previous Minecraft versions due to the moving around of world files between 1.21.11 and 26.1, ensuring items stored in Immersives aren't lost.
  • Note that this does apply to worlds that have already been opened, so lost items will be recovered.
  • If items were present in both the previous Minecraft version and when playing with ImmersiveMC 1.6.0 Alpha 3 on Minecraft 26.1.2, items from the previous Minecraft version are prioritized on a per-Immersive/per-player basis. For example, if a crafting table stored items in both 1.21.11 and in 26.1.2, the items from 1.21.11 are prioritized, and the items from ImmersiveMC 1.6.0 Alpha 3 permanently lost. This was done since ImmersiveMC 1.6.0 Alpha 3 has not been out for long. Note also that items currently present take higher priority over previous versions.
• Fixed ImmersiveMC showing a very incorrect version number in 26.1.2.
