unifont.json contains trailing comma

The assets/minecraft/font/include/unifont.json file obtained from resources.download.minecraft.net contains a trailing comma, which is invalid JSON. The game reads this file in lenient mode, but this is not guaranteed for external tools.

How to reproduce

1. Download https://resources.download.minecraft.net/f4/f40266672fa6cd5c678cbfd5a7fdcfe06e30c629
2. Open the file in a text editor
3. Notice on line 101 that there is a trailing comma

Expected behavior
I expected that all JSON files in assets would be valid
