Soul Fire should damage Fire Immune entities

Currently, Soul Fire works exactly the same as regular fire. I think it would be cool if it had it's own unique properties. Unlike other people, I don't really think it should do more damage, but instead be able to damage things that are normally immune to fire damage.

For example: Wither Skeletons, Blazes, Zombified Piglins, and Ghasts would still be damaged by Soul Fire instead of being immune. Additionally, Players and Mobs with Fire Resistance would also still take damage from Soul Fire.

This would also be a good opportunity to add new visuals for Soul Fire (like how entities catch on fire, but instead it shows blue fire instead) which a lot of people have already suggested. A new Soul Fire enchantment would also be cool, perhaps as a new rare drop from Piglin Bartering, or found in Nether Fortress loot chests.
