Allow Images in Select Menus

[ghost]

Select Menus can have emojis to represent each item which helps, but they're static. You could upload an emoji to a guild the moment you need it, but rate limiting happens and it's not the most efficient way of handing things. Allowing the use of images would prevent the need to do that and allow bots to have any image they want.

Example Usage

(This is the thing that brought up this request haha)

If I were searching a iOS tweaks catalog, I could use the same wrench emoji over and over again or no emoji at all but that's bland. The tweak icon would be different for each result though, so I could also use that, which would make the list look better and act as another way to quickly identify a tweak if you know what you're looking for.
