- Updated pack_format to 18 to support 1.20.2.
- Fix Minecraft resource change (assets/minecraft/textures/gui/icons.png -> assets/minecraft/textures/gui/sprites/hud/experience_bar_progress.png)
Restructured project and combined multiple releases.
I learned more about how resource pack compatibility works and discovered I don't actually need to update the pack_format every time. As long as the resource itself wasn't modified, I don't need to care about incompatibility warnings. This makes maintaining and versioning the project much easier.
- Merged the previous 1.19-1.20 releases into one. The only difference was the pack_format, and nothing actually changed between these releases.
