add exclusions for 3 mods that cause server crashes

`ModernUI-` and `MineMenu-` are included in [Craft to Exile 2](https://www.curseforge.com/minecraft/modpacks/craft-to-exile-2

) and cause server crashes when included. `EasyLAN-` I added manually, but it also crashes the server.

Here are the full filenames:
mods\ModernUI-Forge-1.20.1-3.10.0.4-universal.jar
mods\EasyLAN-v1.2-[1.20.1].jar
mods\MineMenu-1.20.1-1.12.3.jar

After adding the exclusions, the generated server files run without problems
