Villager spawn eggs used on grove, frozen peaks, snowy slopes and jagged peaks don't spawn snowy plains villagers

The Bug

Since all of these biomes are snowy, one would expect spawning snowy plains villagers on groves, frozen peaks, snowy slopes and jagged peaks.

Reproduce

• Get a villager spawn egg.
• Go to a grove, frozen peak, snowy slope biome and jagged peak.
• Use the spawn egg in those biomes.
  Notice a regular villager is spawned.

Expected Result

A snowy variant would spawn.
