Remove extra css class from markdown

Extra css class prevented attachments uploader from functioning correctly.

This caused dropzone wrapper classes to be appended to the wrong class and further prevented the dropzone gem from functioning correctly.

Removing this extra class allows attachment upload to function again while keeping the feature introduced here intact.
