Update Icons for the FeedbackMessage Component

[glendamariegalzote]

Aim of the issue

The FeedbackMessage component currently uses a set of icons that could be updated to align with the Alert and Feedback components for greater design consistency. Replacing the existing icons with those used in these components would help maintain visual uniformity.
