"Required" red text color contrast does not pass WCAG 2.2 AAA

[bacitracin]

Issue Description

This issue was identified in the accessibility audit of the review & confirmation pages of the 526 form.

The color contrast against the grey background is 6.12:1.
The color contrast against the white background is 6.98:1. It should be 7:1 for WCAG 2.2 level AAA.

To fix: Increase the font size to 18, bold the text, or darken the red to get a 7:1 contrast. This is a AAA requirement, so it would just be a minor improvement. This contrast currently passes AA.

Expected severity: a11y-defect-4
Page: review-and-submit
Environment: any screenreader/browser combo
Estimated Level of Effort to fix: low
Design system component involved: Yes
Relevant WCAG success criteria: 1.4.6 Contrast (Enhanced) Level AAA
