This is just a simple update to remain compatible with Minecraft version 1.20.3. None of these changes should cause any issue to worlds updating from a previous New in Town version and/or Minecraft version, but a backup is always recommended when doing so.

General:

• Updated pack format to 26 for Minecraft 1.20.3
• Edited all uses of "minecraft:grass" to use the new "minecraft:short_grass id.
