Dying from void returns wrong message.

**Describe the Bug:**
- When jumping into void it returns message that I've died, not that I felt into the void.

**To Reproduce:**
1. Jump or throw enemy into the void.

**Expected Behavior:**
- In arena config, there is "y-kill-height", and if player dies on specified Y, send message that he felt into the void instead of simply dying.

**Screenshots:**

**System (please complete the following information):**
- OS: Windows
- Server Software: Paper
- Server Version: 1.19.4
- Plugin Version: 23.10-SNAPSHOT

**Additional context:**
- Make another configurable message (but I think that'll be useless)
