Double error announcement for Form field errors

[John-Feola]

Describe the issue
Form-field error is announced twice when user tabs to the field.

URL
https://design-system.w3.org/styles/form-errors.html

Recommended solution
Error should only be announced once.

Additional context
the first reading is from the text being within the input's label and the second reading is from the text being referenced by aria-describedby on the input.

Attached screen recording shows the current behavior:
