Drown-immune mobs are hurt by /damage using drown damage type

The bug:

Mobs immune to drowning will be killed by the drown damage of the /damage command; this is unlike mobs immune to fall damage which take no damage with the fall type inserted in /damage.

Using the /damage with drowning type should not damage drown-immune mobs.

Affected drown-immune mobs:

• Husk
• Zombie
• Drowned
• Zombie villager
• Zombified piglin
• Zoglin
• Zombie horse
• Skeleton
• Stray
• Wither skeleton
• Skeleton horse
• Phantom
• Iron golem
• Axolotl
• Dolphin
• Turtle
• Frog
• Cod
• Salmon
• Tropical fish
• Pufferfish
• Guardian
• Elder guardian
• Squid
• Glow squid
• Ender dragon

Steps to reproduce:

1. Summon any of the above-listed mobs.
2. Use the /damage command:

   /damage @e[type=!player,sort=nearest,limit=1] 30 minecraft:drown at ~ ~ ~

Result:

The mob dies.

Expected result:

No damage is dealt, and the command returns "The entity is immune to this damage type"
