fix: Dashboard list row height does not match other lists

[michael-s-molina]

SUMMARY

Fixes the dashboard list row height to match the height of other lists. This problem was introduced by the Slack Avatar integration.

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

As we can see the row height is not the same between the dashboard and charts list which makes the avatars close to the row separator in the dashboard list.

After the fix, the dashboard list matches the layout of charts/datasets lists and there's a space between the avatars and row separators.

TESTING INSTRUCTIONS

Check that the layout match between lists.

The less custom CSS the better - we should probably enforce a [soft] rule to keep css only in the component library / reusable components
