Villagers' experience and gossips are still retained when converted to zombie villagers and cured

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
