Hide empty fields in the biography details section

Fixes

Fixes microtask T406909

Description

In the author.html template, this fix will hide fields that do not have any value, instead of showing the field label with an empty value.

Checklist

• Maintain codebase practice throughout by using same if statement logic used to hide work_ethnicity
• Use an if statement for each div element (i.e: field) under the Biography details section
• If the value of that field is empty, it will hide the div element altogether
