No HTML formatting in Additional Fields (article metadata)

[mi-les]

Describe the bug In the article metadata, additional fields do not enable HTML formatting. For example, adding links to related material like code and data is not possible.

To Reproduce Steps to reproduce the behavior:

1. Go to article Metadata section
2. Under Additional Fields, the fields are only simple text fields
3. The corresponding setting is under DASHBOARD/MANAGER/SUBMISSION FIELDS
4. Under Kind, none of the options provide the desired functionality (neither Text Area nor Text Field (current) offer no HTML formatting.)
