Swamp Zombie Variant - 'The Swamped'

We have the Bogged as a swamp variant of the Skeleton, so I think Zombies should get a similar variant: The Swamped.

The Swamped would spawn naturally in Swamp and Mangrove Swamp biomes and have a muddy, mossy, waterlogged appearance, making it look like it has been wandering through the swamp for years.

It could function just like a normal Zombie, with no new abilities or drops. The main purpose would be to give Zombies a biome-specific variant and make Swamps feel more unique.

We already have the Bogged, so adding The Swamped would complete the swamp-themed versions of two of Minecraft's classic hostile mobs.
