Edit feature for Nationality field

Closes T405412 Task Description Implemented an inline edit functionality for author data fields in Paulina’s user interface using bootstrap icons and Javascript logic. When a users click the pencil icon, the field becomes editable, allowing them to modify the text and confirm changes using the check (publish) icon. Additionally, I introduced a cancel button that is beyond the initial task scope to enhance usability. This feature restores the field’s original value when users decide not to proceed with their edits, ensuring a more intuitive and user-friendly editing experience.
