Bundle: Error messages and alert accessibility

[AnnaGingle]

Story

As a assistive technology enabled user
I want errors preventing me from moving forward to be clearly called out
so that I can fix the error without confusion

Our error alerts and fields fail the following WCAG criteria today:

• 4.1.2 Name, Role, Value:
• 1.4.1 Use of Color

Acceptance Criteria

• Alert error state: icon screen reader output #2943
• Add icon to text input error state screen reader output #2964
• Be sure to check all pages, including the review page on request, and check using both the org model flag an non org model flag.

Additional Context

@Katherine-Osos mind explaining why @kimberly-a is assigned, is she reviewing this ticket and we should hold off on fixing it until then?

[Katherine-Osos]

@abroddrick It was a mistake. Just unassigned.

@CocoByte It looks like you completed the work for this bundle which includes tickets 2943 and 2964, but those two tickets are open. They look done to me, should they be closed? cc: @Katherine-Osos
