Login.gov required form fields style

[Karla Rodriguez]

Please consider a required form fields style for the Login.gov design system. Partner forms have more optional fields than required fields, so a distinct style for required fields will assist the user in spotting the needed information both in filling out the form and identifying validation errors.

For example, taken from USWDS:
color: #981b1e; content: ' (*required)';
