[MCPE-158736] Mangrove Swamp spawns wrong Zombie Villager type (Parity)

In Java, when a Zombie Villager spawns in a Mangrove Swamp, it spawns with the Swamp outfit.

In Bedrock, when a Zombie Villager spawns in a Mangrove Swamp, it spawns with the Plains outfit.

Testing with a behavior pack, adding

{
            "filters": {
              "any_of": [
                {
                  "test": "has_biome_tag",
                  "value": "swamp"
                },
                {
                  "test": "has_biome_tag",
                  "value": "mangrove_swamp"
                }
              ]
            },
            "add": { "component_groups": [ "swamp_villager" ] }
          },

into zombie_villager_v2.json in the appropriate section resolved the issue for me and my Realm, so I hope it'd be a fairly easy fix to implement properly
