All CardList components now have bottom margin

[samajammin]

Describe the bug

All CardLists now have a bottom margin, which I don't believe is intended. The background color is the same despite the borders:

e.g. on https://ethereum.org/en/get-eth/#country-picker

To Reproduce
Steps to reproduce the behavior:

See example link above.

Expected behavior

I don't think we should have a margin here...

This is what those CardLists use to look like:

Additional context

Looks like it came from this commit?

I suspect @corwintines was only trying to apply this to the staking resource links:

Which I do think look better separated by margins but we should apply to only that instance vs. across the app.
