[ic-card-vertical] Clickable card link styling doesn't match link in Safari

### Summary of the bug
When you hover over a link in Safari it expands the underline to be taller, but when you hover a clickable card, the card title link only moves the underline on hover.

### 📸 Screenshots or code
Link on hover:

Card title on hover:

### 🧐 Expected behaviour
The card title should look like an ic-link

Start by comparing the hover styling of the ic-card-vertical title link with the ic-link behavior shown in the screenshots, focusing on Safari. Update the card title so its underline expands and matches ic-link on hover, then verify the resulting appearance in Safari.
