Mob name colors still don't work with translation/keybind components

MC-181418 was fixed for text, however mobs with pure translate or keybind as names still cannot use colors.

How to reproduce

/summon cow ~ ~ ~ {CustomName:'{"text":"Something","color":"green"}'}

→ ✔ Name is green

/summon cow ~ ~ ~ {CustomName:'{"translate":"item.minecraft.pufferfish","color":"green"}'}

→ ❌ Name is white

Workaround

[{"text":"","color":"green"},{"translate":"item.minecraft.pufferfish"}]
