Update Attachment Text CSS Styles

[ambaldwin]

Currently, the text in the Card component never displays due to a ‘display: none’ in the CSS. This was originally set 3 years ago, so the reasoning of why it was written this way doesn’t exist. An update of this CSS should involve thorough testing of all lengths of text etc.

Goal: update CSS to display the text in the component.
