Inconsistency: Spider jockeys cannot have a Bogged rider, despite other skeletons spawning as riders

In a recent 1.21.90 preview, a longtime bug that caused spider/cave spider jockeys to not spawn with stray or wither skeleton riders was fixed: meaning that now stray spider jockeys can spawn in snow biomes, and wither skeleton spider jockeys can spawn in the Nether.

However, bogged cannot spawn as spider jockey riders when a spider jockey spawns in a swamp biome, which has been the case ever since they were added in 1.21. This now makes it inconsistent when the other skeletons (skeleton, stray, and wither skeleton) can all spawn as spider jockey riders, but bogged cannot.

Steps to Reproduce:

• Go into creative mode and travel to a swamp/mangrove swamp biome

• Set the time to night

• Start spawning spiders/cave spiders using spawn eggs until spider jockeys spawn (this is a 1% chance so it may take a minute)

• Observe what kind of rider the spider jockey has

Expected Result:

• Since it spawned in a swamp biome, the spider jockey has a chance to have a bogged rider (the same logic as strays and wither skeletons)

Observed Result:

• The spider jockey always has a regular skeleton rider
