Biome variants don't match between frogs and farm animals

The variant that spawns in several biomes is inconsistent between the Frog and the Cow, Chicken, Pig, and Sheep spawn behaviour.

As far as I can tell, this has been the case since 25w02a when the variants for the Pig were originally added, and while tweaked since, hasn’t matched up with the Frog behaviour.

Steps to reproduce

1. Go to a biome like the Stony Peaks

2. Spawn a frog

3. Spawn a cow, pig, chicken

Expected result

The frog and the animal have the same variant (cold, warm, or temperate)

Actual result

The frog and the animal have a different variant

Biomes

From what I can tell this happens in 9 biomes. In 7 (Old Growth Pine Taiga, Old Growth Spruce Taiga, Taiga, Windswept Forest, Windswept Hills, Windswept Gravelly Hills, Stony Peaks), a Temperate Frog spawns with a Cold animal, while in the other 2, (Lukewarm Ocean, Deep Lukewarm Ocean) a Temperate frog with a Warm animal.
