Add small type blurb to iota expected mishaps #950

Describe the feature

Mishaps should write a little blurb first, like Impulse expected an entity at index 1 of the stack, but got a list [Creeper]. A lot of people have been getting confused about entities and a lone entity in a list, likely because they glance over the brackets or think it's for decor. Just adding a quick clarification would help UX quite a bit. The way I envision this being implemented is a custom translation key for all iota types, something like "iota.hexcasting:null": "null" and "iota.hexcasting:vec3": "a vector".
