Debug worlds have a second wandering trader at the position where baby mobs spawn

Steps to reproduce:

• Create a new debug world

• Go to the position where the wandering trader spawns (/execute in minecraft:overworld run tp @s -99.23 75.62 -33.66 -508.34 23.82)

Expected result:

There is only one wandering trade at the position for adult mobs because wandering traders have no baby variant.

Actual result:

A second wandering trader at the position where baby mobs spawn.
