Update ImageInput component prop types

[connor-baer]

Effectively reverts #1970.

Purpose

The ImageInput accepts a component prop to render the selected image. This image should be hidden from screen reader users. aria-hidden is more appropriate than alt since it works for any HTML element, not just img.

Approach and changes

• Update the component prop's function signature

Definition of done

• Development completed
• Reviewers assigned
• Unit and integration tests
• Meets minimum browser support
• Meets accessibility requirements
