### Description

Fixes some pictogram related card styling issues.

### Testing instructions

* Review and pay particular attention to Card and Card Group stories, looking for regressions
* Use the Card Group story, with a "Card type" of "Card - pictogram". Then check the "Hide description" checkbox and ensure that the cards are [matching spec](https://www.figma.com/design/oip4K9G1z0v7tLNBbDZzdr/Card-specs-v2?node-id=19-3434&node-type=canvas&t=lwI58ey8t4c8MTqo-0).

### Changelog

**Changed**

- Visual fixes for pictogram cards when there is no card description.
