Summoning a pig with commands or a spawn egg in snowy plains creates temperate pig

The Bug:

Repost of MC-279235 for Bedrock Version.

Steps to reproduce:

1. Enable the Drop 1 2025 Experiment.
2. Go into a snowy plains. Hint: To help you, use /locate biome ice_plains and teleport to the destinated biome.
3. Give yourself a pig spawn egg
4. Use the pig spawn egg in the snowy plains

Observed behavior:
The pig that is spawned is a temperate pig.

Expected behavior:
The pig should be a cold pig, as the biome it got spawned in is cold.
