Add specific mob recipe:

//Specific MOB
event.recipes.createMechanicalSpawnerSpawner(Fluid.of('minecraft:water', 700)).processingTime(8000).mob("minecraft:skeleton;

Add recipe with custom loot:

event.remove({ output: 'minecraft:wither_skeleton'}); //recommended
event.recipes.create_mechanical_spawner.spawner("minecraft:wither_skeleton", Fluid.of('minecraft:lava', 1000))
    .customLoot(
