In 24w37a, the villager's experience, gossips and data will still be retained when the villagers are converted.

Step to reproduce:

1. Find a villager in 24w37a and trade with it
2. Transform the villager into a zombie villager
3. Heal the zombie villager

As shown in pictures, the data and experiences of the villagers are still preserved

Expected:

Villagers' gossips, data and experience points will no longer be retained, as indicated on the changelog in 24w37a
