Description

Currently, we only have a large test story which has all our form components on one page. We should add error state stories for each relevant component.

Problem statement

Users do not have an easy way to preview error states for relevant components. Internally, we don't have an easy way to test error states for these components.

Proposed solution

Add individual error state previews to these components.

We currently offer this error state preview for file input and input prefix only, though the input prefix example doesn't have it's own story and is lacking the form group error markup.
