In the references endpoint the citations field should become type with just a single (enum) value of "web", "news", "journal", "book", or "generic".
- We show only one single value in the type field.
- If there is a single cite tag anywhere in the reference content or there are multiple cite tags with the same value we use that value.
- In other cases (i.e. if there are none or multiple cite tags with different values) we use "generic".
