Update: Fix for Missing Next/Previous Buttons in Minecraft 1.21.4
Issue:
In Minecraft 1.21.4 with the latest Skript version, the "Next" and "Previous" buttons were not appearing correctly in the custom inventory.

Fix:
The issue was fixed by adjusting the logic for determining whether there were additional pages to display. Now, the "Next" and "Previous" buttons are properly shown when there are more pages of bounties to navigate through.

This fix ensures the buttons work as expected in Minecraft 1.21.4 and the latest Skript version.
